Technical Field
The invention relates to the field of XML file processing, in particular to a label clearing method.
Background
The project amount list is a detailed list of names and corresponding quantities of branch project projects, measure projects, other projects, expense projects, tax projects and the like of the construction project. In the project type bidding activities, it is necessary to examine whether each bid document substantially responds to the request of the bid document, conforms to the key terms, conditions and specifications requested by the bid document, has no significant deviation, has no calculation error, missing items, and the like, before evaluating the bid.
The general data amount in the engineering quantity list is more, the prior bidder makes the engineering quantity list which is mainly automatically generated by various construction cost software, and the data packet is mainly in an XML format.
XML, as a kind of semi-structured data, is a common format of data without markup. While XSD (XML schema Definition) is used to describe the structure of an XML document, there is also a standard structure and specification.
Because the list specification format difference of provinces and cities is large, the XSD used for describing different XML documents has various conditions of Chinese, English, full spelling, initial letters and the like, and the data packet formats generated by different construction cost software have certain difference. Therefore, the bid clearing work currently faces the following problems:
(1) the workload and the calculation amount of the index clearing inspection are large, and higher requirements are put forward on the performance of processing logic;
(2) the unified data standard is lacked, and the cost software is usually customized and developed according to various local standards, so that the difficulty is brought to unified standard clearing;
(3) the bid clearing rule depends on various local standards and actual requirements of owners and is difficult to be specified as a specific rule;
(4) the list specification and the like are regulated irregularly, and the change of the XML structure brings a large amount of maintenance and upgrading workload to the traditional clear mark software.
Disclosure of Invention

FIG. 3 is a diagram illustrating parsing of program fields of the XSD standard according to an embodiment of the invention. Fig. 4 is a schematic diagram of a checking rule according to an embodiment of the present invention. FIG. 5 is a tree diagram of an XML document obtained according to the parsed XSD standard in an embodiment of the present invention. FIG. 6 is a diagram illustrating a part project inventory and pricing plans obtained after the de-bidding process is performed according to an embodiment of the present invention. FIG. 7 is a diagram illustrating a part project inventory and pricing plans obtained after the de-bidding process is performed according to an embodiment of the present invention. FIG. 8 is a diagram illustrating the association between the part item list and the pricing tables obtained after the bid clearing process according to an embodiment of the present invention.
In this embodiment:
taking the newly added Shanxi province 2018 standard as an example, the whole clearing standard is configured according to the graph of FIG. 2, after a new standard is added, a list as shown in FIG. 3 is displayed, and the clearing rule adopted by the standard is selected. The rules can be modularly and freely combined and smoothly upgraded and expanded.
After the check is finished, the standard configuration is formally started, and firstly, an XSD corresponding to the standard needs to be imported, for example, the shanxi 2018 standard, and part of the content of the list data specification XSD is shown in fig. 4.
After the XSD is imported, a comprehensive configuration page is entered, necessary key attributes are selected according to each uploaded XSD, and the key attributes defined by the current system comprise:
(1) bidding documents [ document type labels, project names ]
(2) Bidding documents [ document type label, project name, bidder name, total bid price ]
(3) Control price documents [ document type labels, project names, control prices, measure item fees, part item project fees, fees ]
(4) Documentary documents [ document type mark, project name, documentary price, measure project fee, branch project fee, and rule fee ].
The tree diagram of the XML document is obtained by analyzing the analyzed XSD standard, and the display effect is shown in FIG. 5.
After the comprehensive configuration is completed, the configuration of each bidding clearing rule can be started. The configuration parameters of the bid-clearing rule roughly comprise a form path, a display name, a display column, a detection column and other parameters required by the rule. For the example of a compliance configuration, the rules for configuring a form are shown in FIGS. 6 and 7.
The form names in fig. 6 and 7 are "part project quantity inventory and pricing table", the data will traverse through the data under xpath "/economic mark/single project/unit project/part project/inventory", the associated attributes are used to uniquely determine the attribute group of the form, and the content in the example is shown in fig. 8.
The traversal element path is also a relative path for subsequent field positioning of the form, and the relative path for the traversal element path is also used for storage in the subsequent selection process of the display column and the check column.
After the parameters and content configuration of each selected bid-clearing rule is completed, all operations of new rule adaptation are completed. In the subsequent bid clearing process, as long as the previously defined rules are selected, the system can analyze and process the price XML data file according to the XML structure information obtained by the previous XSD, and can quickly begin the bid clearing work after simple parameter setting:
the foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
