S110. Read the target text and record the positions of all paragraphs in the target text, where the target text includes headings of all levels, and each heading is a paragraph.

In one embodiment, for example, in this embodiment, POI is a tool used by java to process documents in Microsoft Office format. The target text refers to text in Word format. There are multiple paragraphs in the target text, and the target text includes various levels. Headings, and each heading corresponds to a paragraph, that is, a heading is a paragraph. Specifically, the target text is read through POI, and each paragraph is marked when reading, so as to record the position of each paragraph.

In an embodiment, for example, in this embodiment, as shown in FIG. 2, the step S110 may include steps: S111-S112.

S111. Read the target text and divide the target text according to paragraphs.

S112: Mark each paragraph in the target text by a serial number to determine the position of each paragraph.

In an embodiment, for example, in this embodiment, the read target text is divided into paragraphs, the target text is divided into multiple paragraphs, and the target text is read one by one in the order from the top to the bottom of the text , Each time a paragraph is read, a mark is added to the read paragraph, where the mark is a serial number, and the serial number specifically refers to the sequence of Arabic numerals, starting from 0 for marking. The details are as follows.

S120: Acquire title names of titles at all levels in the target text according to a preset format.

In an embodiment, such as this embodiment, the target text includes multiple levels of headings, for example, a first-level heading, a second-level heading, and a third-level heading, and there are multiple titles of the same level for each level of heading. The preset format specifically refers to the format of headings at all levels. There are multiple preset formats for headings at each level. The preset format is set according to the fixed heading format of the Word text and the commonly used heading format. For example, the first-level heading is " The first chapter," or "one,", the second-level title is "first section," or "(一),", and the third-level title is "first section," or "(1),". Specifically, first traverse the target text according to the preset format of the first-level title to find the title that meets the first-level title format, thereby obtaining the title name of the first-level title; then traverse the target text according to the preset format of the second-level title to find the title that meets the second-level title The title of the title format is used to obtain the title name of the secondary title; finally, the target text is traversed according to the preset format of the tertiary title to find the title that conforms to the secondary title format, thereby obtaining the title name of the tertiary title. It should be noted that some texts may only have first-level headings and second-level headings. If there are no third-level headings, and no headings that conform to the third-level heading format can be found, then this step is ended and the next step is performed.

S130: Obtain the positions of the corresponding paragraphs of the headings of each level, and determine the start and end positions of the headings of each level according to the positions of the adjacent paragraphs corresponding to the headings of the same level.

In one embodiment, for example, in this embodiment, after obtaining the title names of all levels of headings, first obtain the serial numbers of the corresponding paragraphs of the headings of each level. For example, the serial numbers of the first level headings are 1, 35 and 60, and the second level headings The serial numbers are 5 and 20, and the serial numbers of the three-level headings are 10, 15 and 25, 30. The serial numbers of the corresponding paragraphs of the obtained headings at all levels are used as the starting position of each heading; then two adjacent siblings are selected Title, set the serial number of the title of the same level with the serial number in front to X, and set the serial number of the title of the same level with the serial number in the back to P, according to the preset formula:

Y=P-1

Among them, Y is the end position of the title of the same level with the serial number in front. According to the preset formula, the end position of the title of the same level with the serial number in front can be obtained. Then the start and end positions of the title of the same level with the serial number are (X, Y). For example, if the serial numbers of the first-level titles are 1, 35, and 60, select two adjacent titles of the same level, 1 and 35, where the serial number of the title of the same level with the first serial number is 1, and 1 is the same level with the first serial number. The starting position of the title, the serial number of the title of the same level after the serial number is 35, and the end position of the title of the same level with the previous serial number is calculated according to the preset formula as 35-1=34, thus the title of the same level with the previous serial number is obtained The starting and ending positions of is (1, 34). In the same way, the start and end positions of other titles at all levels are obtained in the same way.

S140. Create a tree structure object, and store the title names of each level of title and the corresponding start and end positions in the nodes of the tree structure object to form a directory of the target text, wherein the tree structure The structure object includes multiple nodes.

In an embodiment, for example, in this embodiment, a tree structure object is created in a java program, and the tree structure object is used to store the title names and corresponding positions of the titles at all levels in the target text. The tree structure object includes multiple nodes, and each node has a unique parent node and multiple child nodes.

The root node is used to store the file name of the target text in order to find the target text. The root node is connected to multiple parent nodes. The title name of the first-level title and the corresponding start and end positions are stored in the parent node. The number of parent nodes corresponds to the number of the first-level title; each parent node is connected to multiple child nodes. The title name of the level heading and the corresponding start and end positions are stored in the child nodes, and the number of child nodes corresponds to the number of second level headings; if the target text has a third level heading, continue to add grandchildren, child nodes and multiple grandchildren The connection, the title name of the third-level heading and the corresponding start and end positions are stored in the grandchildren, and the number of grandchildren corresponds to the number of the third-level headings. That is, the number of levels of nodes is added for storage as many levels of headings as there are, and the number of heading levels corresponds to the number of node levels. For example, as shown in Figure 5.
