如何使用C#和OpenXml访问Word文档中的大纲编号？

我得到文档的主体,并使用它来获取所有段落对象的列表：

var allParagraphs = new List<Paragraph>();
WordprocessingDocument wordprocessingDocument = WordprocessingDocument.Open(wordDocPath.Text, false);
Body body = wordprocessingDocument.MainDocumentPart.Document.Body;
allParagraphs = body.OfType<Paragraph>().ToList();

但是我似乎找不到任何存储该段落旁边的大纲编号的东西.我是否需要抓住文档中段落以外的其他对象以获得每个段落的轮廓编号(如果有)？

我说的轮廓编号出现在以下屏幕快照中这些标题的左侧：

不幸的是,即使我知道ParagraphProperties.OutlineLevel是word文档中大纲的一部分,它也是null.

首先,我建议您从here下载Open XML Productivity工具.一旦知道文件的底层xml看起来是什么样,就很容易解决该问题.

<w:p w:rsidR="004265BF" w:rsidP="00AD13B6" w:rsidRDefault="00AD13B6">
 <w:pPr>
  <w:pStyle w:val="ListParagraph" />
  <w:numPr>
   <w:ilvl w:val="0" />
   <w:numId w:val="2" />
  </w:numPr>
 </w:pPr>
 <w:r>
  <w:t>Requirements</w:t>
 </w:r>
</w:p>
<w:p w:rsidR="00AD13B6" w:rsidP="00AD13B6" w:rsidRDefault="00AD13B6">
 <w:pPr>
  <w:pStyle w:val="ListParagraph" />
   <w:numPr>
    <w:ilvl w:val="1" />
    <w:numId w:val="2" />
   </w:numPr>
  </w:pPr>
  <w:r>
   <w:t>Performance</w:t>
  </w:r>
</w:p>

在上面可以看到仅几段的XML.每个段落都有对应的,其中包含.

每个Word文档都包含许多不同的XML文件,这些文件用作对整个文档正文中使用的样式和值的引用.有关轮廓,请参见Numbering.xml.

这里的每个numId都引用numbering.xml中的AbstractNumId,而后者又引用了同一文件中的abstractNum.您可以从那里获取您的提纲编号.

我知道这听起来可能很乏味,但这是唯一的方法.

.

祝一切顺利！
