In one aspect of the embodiment of the application, a method for processing resolution mapping of HL7V3 standard/FHIR standard is provided, as shown in FIG. 1, comprising the steps of mapping relation configuration and data conversion.
Specifically, the mapping relation configuration includes the following detailed steps:
s11, importing an HL7V3 data template, and automatically analyzing:
and respectively carrying out recursion analysis on the imported HL7V3 source data template and the HL7V3 target data template to respectively obtain a source data XPath tree set and a target data XPath tree set.
Specifically, when the imported HL7V3 source data template/HL 7V3 target data template is selected to automatically generate XPath, namespace added with XML is supported to carry out XML analysis, because the source XML data structure is complex, the direct analysis can generate the same XPath path data, node screening conditions can be configured, the bottom logic uses recursively to analyze XML, the obtained XPath path corresponding to each XML node is compared with whether the current XPath path is repeated in the whole tree, if so, if all child nodes of the lower three layers have attributes matched with screening node conditions, screening attributes are added to XPath to obtain the XPath path with the screening conditions, as shown in figure 2, the XPath path with the unique path is obtained, and the XPath tree set is put into the XPath tree set according to the hierarchical relation when Xml is analyzed, so that the source data XPath tree set and the target data XPath tree set are obtained, and the target data XPath tree set is used for data construction in the later period.
Although there are many tools or methods for quickly analyzing XML from the general technical layer, the data similar to HL7V3 standard has multiple-attribute multi-node characteristics, and XPath analyzed from conventional data cannot meet the mapping requirement of subsequent nodes without screening conditions. In the step, the comparison calculation of the peer node, the child node and the grandchild node is repeatedly carried out in the XML data recursion process so as to construct a unique XPath node, namely the XPath path of the unique path.
S12, checking data, namely checking the data basic length, the value range, the regular specification and the base number in the source data XPath tree set and the target data XPath tree set, and caching after the data are checked to be qualified so as to be called for the data conversion step.

Value node XPath configuration:
in the mapping operation, not all nodes will map, if the whole Xpath tree set is traversed, the time consumption is large, so the mapping result is based in advance, therefore in this step, the obtained target data Xpath tree set is contracted based on the obtained value node Xpath mapping information, and the target Xpath tree set with a mapping relation is obtained, as shown in fig. 3, after the tree is contracted, the time consumption of the subsequent cycle is reduced.
S24, data checking and target data value replacement:
by this step, four data messages have been obtained: the method comprises the steps of inputting XML document objects of source data, a source data XPath tree set, a complete structure target data template and a target XPath tree set with a mapping relation. When the step is carried out, data structure detection is carried out based on the XML document object and the acquired source data XPath tree set, the source data XPath tree set is circulated, the value of the corresponding node is obtained from the XML document object through the XPath path, and the detection of the length and the value range is carried out:
