Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The various embodiments and features of the embodiments described below may be combined with one another without conflict.
Example 1
The embodiment of the application provides a method for reading and analyzing a package for long-term storage of an electronic file, which does not need a programmer to write a package fixing structure into a code in advance, but provides guidance for the analysis process of the package by configuring the package structure on line, and can provide flexible configuration according to the package structure or post-modification, so that the efficiency for reading and analyzing the package for long-term storage of the electronic file can be improved, the construction period of the project is reduced, and great benefit improvement is brought to users. The technical means includes that the method includes that a parsing program is guided to perform hierarchical parsing on package data based on definition of content fields of a type of parsing files in a package; and realizing automatic positioning of the target file for realizing layer-by-layer analysis on the path binding in the analysis file.
Referring to fig. 1, the method for reading and analyzing the package for long-term storage of the electronic file includes the following steps:
step S101: and constructing the intra-packet path information of the archive metadata file by using a placeholder processing method based on the handover list information in the target encapsulation packet, wherein the handover list information is information used for describing the archive entry of the encapsulation packet in the target encapsulation packet.
The electronic file analysis flow in the package is initiated by adopting a field clue, and in the analysis process, the analysis file is taken as a unit, and each analysis is carried out aiming at a specific file. Thus, it is necessary to know the location of the parsed file. If the analysis file has a fixed position, the analysis file can be directly acquired. However, the range of the electronic file is larger and larger, so that the position of the analysis file corresponding to the electronic file is not determined any more, and accurate acquisition is difficult to directly perform. In the above step, the intra-package path information of the archive metadata file is constructed by using the placeholder processing method based on the handover list information in the target package, and one or more specific values can be constructed for the content to be analyzed, so that the subsequent processing is facilitated.
Illustratively, as shown in fig. 2, there is a fixed "handover list xml" at the top of the package, which describes file entries in the entire package, and basic information of two files, such as full-number (123), case numbers (0001 and 0002), and file numbers (0001 and 0002), from which the intra-package path of each file metadata file, such as "{ full-number }/{ case number }/XSD { case number }. Xml", is constructed by a placeholder method, and two intra-package paths of file metadata files, such as 123/0001/XSD0001.Xml and 123/0002/XSD0002.Xml, are constructed by such placeholder format. It can be seen that when constructing the path, the program can acquire the data in the placeholder in an upward backtracking searching mode through the tree structure, and the same group of the file number and the file number are isolated through the tree node, so that two illegal results, namely 123/0002/XSD0001.Xml and 123/0001/XSD0002.Xml, cannot occur.
In some embodiments of the present invention, the constructing the intra-packet path information of the archive metadata file based on the handover manifest information in the target encapsulation packet using the placeholder processing method includes: and respectively acquiring metadata name information of all electronic files in the target package according to the handover list information, and filling the sequentially acquired metadata names of the same electronic file into the same group of preset placeholders to obtain intra-package path information of all archive metadata files in the target package.
In the above step, for the metadata names of the same electronic file, the metadata names are directly filled into the placeholders of the same group according to the acquired sequence, so as to generate a complete path of the corresponding electronic file (i.e. the path information in the package of the corresponding archive metadata file), so as to inspire the analysis process of the subsequent files of other types, and finally complete the analysis process of the files in the whole package.
In some embodiments of the present invention, the method further includes performing data cleansing on the obtained intra-package path information of the archive metadata file, where the data cleansing includes: and judging illegal characters on the obtained path information in the package of the file metadata file, and deleting the path information in the package of the file metadata file judged to comprise illegal characters.
For the method of constructing the intra-packet path filled with placeholders according to the acquisition sequence of the metadata names, some illegal and unusable intra-packet paths may be constructed, so that illegal character judgment can be performed on the intra-packet paths, and deletion processing is performed on the non-conforming intra-packet paths, so that the construction accuracy of the intra-packet paths can be improved.
Referring to fig. 5, in some embodiments of the present invention, the method for constructing intra-packet path information of an archive metadata file based on handover manifest information in a target encapsulation packet by using a placeholder processing method includes:
respectively acquiring metadata information of all electronic files in a target package according to the handover list information, and performing isolation processing on metadata of different groups based on a data structure of preset tree metadata, wherein the isolation processing comprises the following steps: maintaining a multi-tree data structure in the parsing process, when the node type needing to isolate the metadata is encountered, performing bifurcation processing on the multi-tree, and placing the metadata in the subsequent child nodes in different child nodes; when the placeholder is encountered, the source-tracing search is performed upwards until the base node is found.
When constructing a field by a placeholder method, particularly when constructing a field for a loop structure, an isolation operation of metadata needs to be considered. For example, referring to FIGS. 3-4, there are two file numbers and metadata names parsed from the handoff list xml file, but only one contiguous group is meaningful in terms of the placeholder formation path (i.e., 0001 and XSD0001, 0002 and XSD 0002), which requires that the child node be the metadata (parent node) and not the collateral metadata (sibling node) to be employed in accurately constructing the placeholder path. Because the data of the brother nodes are different individuals of the same type of data in the parsing process, such as a plurality of files in one package, the direct data are different in content though the fields are consistent, and the direct data should be processed separately.
Thus, in the above steps, by adopting a data structure of tree metadata to perform different component data isolation, illegal results can be avoided from being generated when generating character strings according to placeholders (when generating intra-packet paths) to influence the accuracy of intra-packet path construction. Through the structure and the query mode, the purposes of unique and determined construction results can be realized.
Illustratively, in some embodiments of the present invention, acquiring metadata information of all electronic files in the target package according to the above-described handover manifest information, respectively, includes: if the corresponding electronic file is an XML type file, the program will extract the data in the XML type file according to the set field list, and create a new tree node for the array type data. Thus, the same type of metadata of different arrays can then be isolated based on the data structure of such tree metadata nodes. Wherein, the isolation processing includes: maintaining a multi-way tree structure in the parsing process, when the node type needing to isolate the metadata is encountered, carrying out bifurcation processing on the multi-way tree, and placing the metadata in the follow-up sub-nodes in different sub-nodes, namely separating the same type of metadata in the brother nodes, wherein only the follow-up data query and the path construction process can trace upwards for searching, and the brother nodes of the same level can not be searched; when the placeholder is encountered, the source-tracing search is performed upwards until the base node is found.
With continued reference to fig. 1, step S102: and acquiring the file metadata file in the target package based on the in-package path information of the file metadata file, analyzing the electronic file name contained in the corresponding file metadata file, and constructing the in-package path information of the electronic file by using a placeholder processing method based on the file name and the in-package path information.
In the above steps, after the path information in the package of the archive metadata file is constructed, the path is further perfected, and the path information in the package of the electronic file is constructed for positioning to the specific electronic file. For example, referring to fig. 2, after two intra-package paths of archive metadata files are obtained, the parsing process is continuously started on the basis of the two intra-package paths to complete the parsing of the two metadata files, and by parsing the file names contained in the pieces, intra-package paths (123/0001/data_1. Pdf, 123/0001/data_2.Pdf, 123/0002/data_3.Pdf, 123/0002/data_4. Pdf) of the electronic files can be continuously constructed, so that the reading and parsing of all files in the package can be finally completed.
Step S103: and reading and analyzing the target electronic file in the target package based on the path information in the package of the electronic file. Therefore, specific and complete path information in the package of the electronic file can be read and analyzed in a targeted manner, a programmer is not required to write the fixed structure of the package into a code in advance, accurate reading and analysis of electronic files with various types and numbers can be realized, the reading and analysis efficiency of the package stored in the electronic file for a long time is improved, the construction period of the type of project is reduced, and great benefit improvement is brought to users.
In some embodiments of the present invention, a plurality of different parsing models are included, each for parsing a different type of parsing file;
the reading and analyzing the target electronic file in the target package based on the path information in the package of the electronic file includes: and reading the target electronic file in the target package based on the path information in the package of the electronic file, and carrying out analysis processing according to the type matching corresponding analysis model of the target electronic file. By way of example, the corresponding matching parsing may be performed for the types of XML structures, non-physical file structures (pure path constructs), common files, etc.
As shown in fig. 6, for a package, it may be composed of multiple files, where one file contains multiple electronic texts (such as PDF or OFD files), and by inputting an analysis model into the system, multiple types of analysis files are set, and each file adopts a set of field analysis methods, and finally, the analysis process of all files in the whole package can be completed. It should be noted that, the above-mentioned analysis model may be a total model (including analysis processes of multiple different analysis models), or may be different analysis models that are distinguished by types, so that the analysis models of the corresponding types may be matched according to the types of the target electronic files, so as to implement targeted analysis processes.
