Model OSI layer 7s（Application layer）Medical information exchange agreement.At present, HL7 agreements have proceeded to the third edition, i.e.,
HL7V3。
When realizing the interaction of medical information between the medical system based on HL7V3, often refer to need local life
Into two-dimentional relation table be converted to send after XML file and come from other medical systems to other medical systems, or by what is received
XML file be converted to two-dimentional relation table after store to local.In the related art, mainly using XML reflection methods.Wherein,
Realize that the process of mapping is generally divided into two parts：Configuration maps and using mapping relations conversion XML.
XML（Extensible Markup Language, extensible markup language）It is a kind of description data of structuring
Language, due to its open and scalability, it is widely used in data interaction and data storage aspect at present；XML document master
To be made up of elements such as label, label value, attribute, property value, special handling instruction, annotations.At present, XML analytic technique master
There are two kinds：SAX（Simple API for XML）And DOM（Document Object Model）, two kinds of technology realization principles
It is different.SAX is parsed based on event triggered fashion；XML document is then disposably parsed into one by DOM by DOM parser
The individual object tree being stored in internal memory, the operation to object tree is converted into XML random operation.Therefore, generally current DOM
Due to the convenience of its operation, turn into main flow XML parser method substantially.
When by operating the node locating in dom tree progress XML, mainly XPath technologies are used.XPath uses path
Expression formula chooses the node or set of node in XML document；These path expressions and file system in conventional operating systems
Path expression is closely similar.The path can be absolute path or relative path.Path expression can have
Predicate (predicate), asterisk wildcard and operator.Also containing 100 built-in canonical functions are had more than, these functions are used for XPath
String value, numerical value, date and time compare, node processing, series processing, logical value etc..
However, existing DOM analytic techniques still have performance deficiency, it is mainly manifested in：XPath is mainly according to node road
The criteria character string expression such as footpath and node attribute values, to parse localization of XML, during parsing XPath, it is main and by time
Joint-running point comparison element title and the character string of element value judge to position；Therefore, especially when XML document handles relatively more, text
Shelves are bigger, and when level is deep and condition is more complicated, it frequently parses XPath expression formulas and traverse node compares character
String can directly embody the defects of parsing positioning performance is slow.

XML template configurations instrument 302：For the configuration for the XML template files for carrying out standard, XML and CDS mapping is generated
The information such as the various supporting mark of correlations such as relation, the new XML template files comprising annotation identifier, position encoded, and save as
Integrated configuration information table（That is allocation list）.
Further, when being configured to allocation list, automatic sequence travels through the XML masterplate files of standard, for each member
Element is generated for capable of rapid positioning position encoded and annotation identifier；It is position encoded to be stored in allocation list, annotation identifier
It can be inserted into XML template files, form the new new XML template files for not influenceing original structure；Match somebody with somebody to mapping relations
When putting, to need store dynamic service data each node elements by configuration tool, manual configuration correspond to CDS title and
Its corresponding field name, the mapping relations are matched by title, i.e., must construct initialization in subsequent conversion application has
There must be the field name in mapping in the CDS examples of corresponding title and the field of CDS examples, configuration is otherwise reported in transfer process
It is abnormal；During configuration data collection node, circulation mark can be marked:Or 1..n, 0..n for constraint expression loop body interior nodes weight
Plural number, 0..n represent that the node elements are optional, can not had, it is possibility to have a plurality of repetition；If without when, it should delete the section
Point；1..n it can not be sky to represent the node elements, it is necessary to occurred once, it is also necessary to there is value, node can also repeat repeatedly,
Expression contains a plurality of business record.
CDS turns XML modules 304：For foundation allocation list, by the business datum two in CDS the or CDS groups in operation system
The Content Transformation of dimension relation sheet form is into the XML file and output for meeting HL7V3 standard form XML structures, as HL7V3 forms
Messages application.
Further, during CDS turns XML, if equipped with position encoded, preferential use in allocation list.Wherein,
Every two are one section in position encoded, a level in every section of corresponding dom tree（That is level）, the order of section corresponds to hierachy number.
Such as " 010201 " includes three sections, and first paragraph 01 represents the 1st node elements of first layer, second segment 02, represents the 2nd of the second layer
Individual node elements, the 1st node elements of the 3rd section of 01 expression third layer.When being positioned to DOM node, directly by hop count
Child node level is decomposed into, switchs to respective layer time son node number group subscript by two in section are position encoded, quickly directly positioning
Node, such as：It is assumed that position encoded is 01020302, then parsing operation is proceeded by from root node root：“root.item[01]
.item [02] .item [03] .item [02] " is directly positioned, and according to the CDS titles and field name mapped in allocation list, is read
Go out corresponding field value in CDS of the same name and be assigned to node elements.
XML turns CDS modules 306：The XML file of incoming business datum is received, reads allocation list, it is according to configuration that XML is literary
Business datum in part reads and write in CDS corresponding field, exports CDS files.
Further, during XML turns CDS, according to absolute path and relative path in allocation list and annotation mark
Symbol, localization of XML interior joint element.Wherein, it is preferential to use if there is annotation identifier in XML, can fast positioning；Such as nothing in XML
Annotation identifier, then XPath paths can only be used, it is preferential to use wherein if relative path, if without relative path, only
Absolute path can be used, i.e., positioning be parsed by XPath.
1st, XML template configurations instrument 302
Fig. 4 is the schematic flow diagram that the XML template configurations instrument of embodiment illustrated in fig. 3 performs the configuration to XML templates.
As shown in figure 4, the exemplary flow that XML template configurations instrument 302 performs the configuration to XML templates includes：
Step 402, XML standard form files are loaded, are initialized as dom tree；Because the method for the present invention is to be based on XML moulds
In plate file basis, so the processing of the dynamic structure XML if not normal structure form of having an agreement, does not apply to this side
Method.
Step 404, DOM tree node element is traveled through, configuration tool can extract DOM structure and each section automatically when loading
Point element, including the element such as label, label value, attribute, property value, special handling instruction, annotation；To each node elements by tree
Shape layer of structure deploys, and each element saves as a record, and instrument is suitable automatically according to the level and element of dom tree type structure
Sequence, it is each Element generation absolute position encoder；Extract the hierachy number of each element, XPath complete trails be stored in each it is right
In the record for answering element.
Step 406, manual configuration XML data set node and field node, the mapping configured between XML node and CDS are closed
System, if being provided with data set node, subordinate's child node of the node can be all automatically generated relative to the data set node
Relative position encodes and relative XPath paths, is also stored in allocation list record.
Step 408, the cycle labeling of data set node is set, when there is provided during data set node, marking the data set
The cycle labeling of node, 0..n represent that the node is optional, can repeatedly, if during without content, it should delete the node；
1..n represent that the node is essential, can be repeatedly；If XML duplication of name label nodes are relatively more, this in HL7V3 standard x ML,
Label duplication of name is commonplace, because tag name is relatively more abstract, in order to embody expression different business implication, comes often through property value
Constraint definition, the business implication of sometimes one label node element have also relied on contextual tab and its property value, this complexity
Expression, using at corresponding XML node, annotation identifier is added, be so not shadow because annotation identifier name requires unique
Primary standard XML semantic structures are rung, and XPath and condition positioning can be simplified with annotation identifier indirectly；When configuration addition annotation
After identifier, because influencing whether original position encoded order, XML template files and allocation list can refresh guarantor automatically
Deposit.
Step 410, allocation list and new XML template files are preserved.
2nd, CDS turns XML modules 304
Fig. 5 is that the CDS of embodiment illustrated in fig. 3 turns the schematic flow diagram that XML modules perform the form conversion to CDS files.
Perform the exemplary flow of the forms of CDS files conversion is included as shown in figure 5, CDS turns XML modules 304：
Step 502, initialize, load allocation list, be buffered in C in internal memory, initialize storehouse DS, CS, increase list, delete
List；Storehouse CS is used to preserve nested node pointer, and storehouse DS is used for the record position label for preserving nested CDS；Increase row
It is used to keep in the XML node subtree pointer for needing to newly increase when circulation to be recorded in table, delete list should in XML for keeping in
The node pointer of deletion, to avoid influenceing former XML formwork structures order in the process, the node processing in two lists, it is placed on
CDS turns after XML processing is fully completed, before terminating, the node in delete list to be deleted to the XML after processing one by one, will be increased
Node in list increases in nearly XML one by one.
Step 504, successor parameter CDS array B are received, type of service is read from B, are filtered in C to the type of service phase
Whole configuration records of pass；It is to support multiple two-dimentional relation table CDS, CDS arrays suitable using CDS array forms as ginseng is entered
Sequence is related, and mapping relations are to correspond to the CDS joined in CDS arrays in order number in allocation list.
Step 506, the XML template files of type of service are corresponded to from load configurations, are instantiated as dom tree D, mobile configuration
Table C records Cn to first bar（n=1）.
Step 508, C current records Cn is read.
Step 510, judge whether Cn rows terminate, if C rows terminate, perform step 538, otherwise into step 512 or step
Rapid 532.
Step 512, Cn is data set node type, and CS stacks are sky, then Cn location tags stacking CS.
Step 514, judge whether DS stacks are empty.If DS is sky, step 518 is gone to, if DS is not sky, into step
516。
Step 516, judge whether the hierachy number of current data set node is more than or equal to the hierachy number of DS top-of-stack pointer nodes,
If so, then going to step 524, step 518 is otherwise performed.
Step 518, read that Cn interior joints are position encoded and CDS, D is to corresponding node element for positioning, by node elements pointer
Stacking CS, CDS move on to first bar record position, by CDS and current recording position label stacking DS.
Step 520, judge whether CDS is empty, is such as sky, then into step 522, such as not to be empty, then into step 503,
Move C to next record.
Step 522, add CS stack tops node pointer and add delete list, DS, CS pop, continuous moving C to next note
Record, until record of the next hierachy number more than or equal to current hierachy number, go to step 508.
Step 524, judge whether CS stack tops CDS records terminate, such as terminate to perform step 528, otherwise perform step 526.
Step 526, the new node of DS top-of-stack pointer referents is replicated, addition new node pointer moves into increase list
Dynamic C is recorded back to CS stack top label positions, subsequently into step 530.
Step 528, if DS, CS are not sky, DS pops, and CS pops, and then goes to step 530, that is, moves C to next note
Record.
Step 530, mobile C to next record.
Step 532, Cn is record set node type.
Step 534, position encoded (relative position coding, absolute position encoder) fast positioning D corresponding nodes member is preferentially taken
Element, it is such as no position encoded, then take XPath paths（Relative path, absolute path）Positioning.
Step 536, field value in CDS is read from Cn configuration and is written to the node elements or attribute navigated in D
Value, then go to step 530, mobile C to next record.
Step 538, storehouse DS, CS are emptied；Handle delete list, increase list；If delete list is not sky, travel through
Increase list, one by one increase to increase list middle finger pin knot point in D；If delete list is not sky, the deletion pair from D one by one
Answer node；Two lists are emptied, D is saved as into XML outputs, terminates to exit.
3rd, XML turns CDS modules 306

Perform the exemplary flow of the form of XML file conversion is included as shown in fig. 6, XML turns CDS modules 306：
Step 602, incoming parameter XML is received, is initialized as dom tree, the type of service according to corresponding to XML, initializes phase
Corresponding CDS.
Step 604, XML allocation lists are loaded, corresponding configuration record in allocation list is filtered out by type of service, remembers from first bar
Record starts, and traversal reads configuration record information one by one.
Step 606, judge whether there is annotation identifier in allocation list record, if any step 608 is then performed, performed as without if
Step 612.
Step 608, judge annotation identifier is whether there is in DOM, if any then execution step 610；As performed step 612 without if.
Step 610, DOM node element is retrieved by annotation identifier, reads node elements value, according in allocation list record
Mapping relations, write a value into corresponding CDS in respective field, perform step 614.
