ApachePoi 的 XWPFDocument 中存储的列表信息在哪里? [英] Where are List informations stored in ApachePoi's XWPFDocument?

问题描述

我想合并两个或多个 docx 文件(将它们相互附加)或将文档的一部分 (XWPFParagraph) 移动到其他位置.

I want to merge two or more docx files (append them after each other) or move one part of the document(XWPFParagraph) to other place.

问题是列表总是在这样的操作后中断.假设我们在一个包含序列号的文档中有一个列表，然后我们在另一个包含项目符号或字母的文档中有其他列表.比复制后所有的项目符号都变成数字(或更糟糕的数字，从上一个列表结束的地方开始).

The problem is that listings always breaks after such an operation. Say we have a listing in a document which has sequence numbers then we have other listing in another document which has bullets or letters. Than after the copy all of the bullets becomes numbers (or worse numbers which starts from where the previous listing has been ended).

我尝试了几种解决方案:
- 遍历 BodyElements 并手动复制段落和表格，例如 此处.
- 将 newBody 附加到现有的像这里一样 这里

I have tried several solutions :
-traversing BodyElements and copying Paragraphs and Tables by hand like here.
-attaching a newBody into an existing one like here here

除了页面范围样式之外，它们运行良好.但房源从来没有.这是否意味着列表符号被存储为页面范围的信息(否则它会被 XWPFParagraph 成功复制)?如果是，那么为什么和在哪里?

Aside from page scoped styles they work well. But the listings never. Is that means the listing symbols are stored as page scoped information (otherwise it would be copyied successfully with the XWPFParagraph)? If yes than why and where?

我已经深入研究了 javadoc:https://poi.apache.org/apidocs/dev/org/apache/poi/xwpf/usermodel/XWPFDocument.html
但找不到有关列表的任何信息.

I have dig myself into the javadoc: https://poi.apache.org/apidocs/dev/org/apache/poi/xwpf/usermodel/XWPFDocument.html
But couldn't find anything about the listings.

推荐答案

Office Open XML 文件格式的 Word 编号(编号列表但项目符号列表)被存储在 *.docx ZIP 存档的 /word/numbering.xml 中.有描述列表格式的 abstractNum 元素和引用 abstractNum 的 num 元素./word/document.xml 的段落中引用了 num 元素的 numId 以设置该段落中应使用的编号格式.引用相同 numId 的段落在同一个列表中.引用不同 numId 的段落在不同的列表中.

The Word numberings (numbered lists but bullet lists also) in Office Open XML file format are stored in /word/numbering.xml of the *.docx ZIP archive. There are abstractNum elements describing the list format and num elements referencing the abstractNum. The numId of the numelements are referenced in paragraphs of /word/document.xml to set which numbering formats shall be used in that paragraph. Paragraphs referencing the same numId are in the same list. Paragraphs referencing different numId are in different lists.

在 apache poi 中有 XWPFNumbering 表示文档部分 /word/numbering.xml 和 XWPFAbstractNum 代表abstractNum.

In apache poi there are XWPFNumbering representing the document part /word/numbering.xml and XWPFAbstractNum representing the abstractNum.

直到现在，如果不使用低级 ooxml-schemas 类，就无法从头开始创建 XWPFAbstractNum.

Until now there is no way creating XWPFAbstractNum from scratch without using the low level ooxml-schemas classes.

另外，据我所知，由于需要处理不同的 Word 文档，所以没有简单的方法来合并 /word/numbering.xml 文档部分/word/numbering.xml 中的不同 Id 以及它们在 /word/document.xml 中的出现.这是非常复杂的，我不知道有什么免费的库可以正确地做到这一点.

Also, as far as I know, there is no simple way to merge /word/numbering.xml document parts of different Word documents because of the need handling the different Ids in /word/numbering.xml as well as their occurrences in /word/document.xml. This is very complex and I do not know any free library which can do this properly.

总的来说，据我所知，由于Word文件格式的存储复杂，所以没有简单的方法可以将不同的Word文档合并在一起.使用免费代码提供的所有可能性只有一半有用(遍历和复制)，如果没有错误和无用(简单地一个接一个地附加多个文档正文).

In general, as far as I know, there is no simple way to merge different Word documents together because of the complex storage in Word file formats. All provided possibilities using free code are only halfway useful (traversing and copying), if not wrong and useless (simply attaching multiple document bodys one after the other) at all.
