Description

Multi-line text searching and replacing method and system thereof Technical Field The invention relates to the technical field of intersection of artificial intelligence and information retrieval, in particular to a multi-line text searching and replacing method and a system thereof. Background In existing text editors (e.g., microsoft Word, WPS, code editors) and various specialized text processing systems, find replacement functions are one of the most basic and important functions. However, in processing complex text, the prior art has the following technical problems: (1) The head and tail spaces influence the index positioning problem that when text searching and replacing are carried out, the head and tail spaces (including blank characters such as spaces and tab making) of the text line can directly influence the calculation of the character index. For example, a line of text is preceded by 2 spaces, and matching directly by character index may result in offset errors. The prior art either ignores spaces entirely (which may result in a mismatch) or requires a strict match (poor user experience), lacks a mechanism to intelligently handle head-to-tail spaces while maintaining accurate positioning. (2) The problem of matching across multiple lines is that conventional search alternatives are typically based on a single line of text or an entire block of text, making it difficult to achieve an exact correspondence of "multiple line search content" to "multiple line replacement content". For example, a user may need to replace three lines of the operating steps with four lines of new steps, which requires accurate identification of the matched start and stop lines and maintenance of the structural integrity of the replaced text. (3) Fuzzy matching and wild card support problems-professional field text (e.g., power ticket) often contains variable parts (e.g., device name, number, etc.). Existing wildcards (e.g., x) are simple to implement, but it is difficult to correctly pass matching "fuzzy terms" to the corresponding locations (e.g., \1, \2 placeholders) of the replacement text in multiple line substitutions. The extraction and transfer of ambiguous terms is particularly complex, especially in a multi-line context. Disclosure of Invention The invention aims to provide a multi-line text searching and replacing method and a system thereof, which solve the technical problems. To achieve the above object, according to a first aspect of the present invention, there is provided a multi-line text search replacement method, comprising the steps of: acquiring an original multi-line text to be processed, and a multi-line searching content and a multi-line replacing content which are input by a user; Preprocessing the original multi-line text, the multi-line searching content and the multi-line replacing content respectively, removing head and tail spaces of each line, and obtaining corresponding logic text, logic searching content and logic replacing content respectively; judging whether the logic searching content contains a preset wildcard or not; If the logical text does not contain the preset wildcard, executing a first branch flow, performing simple character string matching on the logical text to obtain a logical index searching result, converting the logical index searching result into an original character index by using a preset index mapping relation for positioning, and executing simple replacement operation; if the fuzzy item list and the starting and stopping row index of the matching block are successfully matched, positioning is carried out by utilizing the index mapping relation, and fuzzy replacement operation of inserting the fuzzy item list into the placeholder is carried out; After the replacement operation is completed, the leading and trailing spaces of the text are restored. Further, the preset index mapping relationship is established by the following manner: establishing a bidirectional mapping dictionary between an original index and a logical index from which the head and tail space of each row is removed; The keys of the first mapping dictionary are character indexes of the original text, the values are corresponding indexes in the logical text, the keys of the second mapping dictionary are corresponding indexes in the logical text, and the values are character indexes of the original text. Further, the performing simple string matching in the first branch flow specifically includes: Obtaining a logical index searching range according to the original index searching range and the first mapping dictionary; and searching the logic searching content in the logic index searching range. Further, the performing the row-wise sliding comparison in the second branch flow specifically includes: analyzing each line of searching templates, and intelligently matching with the target line; And if all the lines of the multi-line searching content are successfully matched in sequence, recording the mu
