Description

Technical Field

[0001] The present invention relates to the field of digital management of aviation technical materials, and particularly to a document generation method and system based on modular division of XML aircraft technical data. Background Art

[0002] XML (Extensible Markup Language) is a markup language for storing and transmitting data, with high flexibility and scalability, and has characteristics such as high standardization, structured data representation, easy parsing, and strong interoperability. Its technical background and application scenarios are as follows:

[0003] XML can represent data with a clear hierarchical structure, making information easy to understand and process. Many programming languages and platforms provide support for XML, including libraries and tools for parsing and generating XML documents. Due to its text format, XML can be conveniently transmitted between different operating systems and programming languages, making the integration between systems smoother. At the same time, XML is a standard recommended by the World Wide Web Consortium (W3C) to ensure its consistency and readability globally.

[0004] There are a wide variety of aircraft technical materials, among which the technical materials for guiding aircraft maintenance involve the most content and the largest amount of data. The writers of technical materials often need to spend a lot of time organizing, adjusting, modifying, and optimizing data, which is time-consuming and laborious. At present, with the continuous development of the Interactive Electronic Technical Manual (IETM) technology, higher requirements are put forward for the digitization and structuring of various types of aircraft technical materials. There is an urgent need for a time-saving and labor-saving method for dividing the program class data schema of aircraft technical materials based on the XML language. Using the XML language, the content structure in technical materials can be structured, improving the accuracy and reducing the complexity of technical material compilation. Summary of the Invention

Build a tree structure division model and divide the program general information based on the tree structure division model <cominf>Conditions that elements and main program elements should satisfy <prerqmts>Element, main program information <maprodu>Partition the elements. In the tree - shaped structure partitioning model, define the XML element tree as a recursive structure T, and the node set V and edge set E satisfy:

[0080]

[0081] Among them, V0 = T = {comInf, preRqmts, maProdu, cloRqmts} is the root node set, Sub(v) is the set of sub - elements of node v, and the depth of the XML tree is described by the recursive level K for dynamic expansion.

[0082] Specifically, it includes the following sub - steps:

[0083] S21. For <cominf>The data of the elements is divided using a tree structure. <cominf>The element includes the program name <tle>, Picture <fig>, Picture group <figalts>And remarks information <not>。
