我正在构建的应用程序为我工作的公司生成提案文档。这是一个复制，替换和删除DOCX文件和XLSX文件的特定部分的复杂系统。我在生成提案的过程中使用XML powertools“DocumentBuilder”来组装文档。我遇到的问题如下。由于模板文件的年限以及我必须处理的绝对数量的选项，“文档”构建器最终忽略了整个文档长度的一些边距设置。我想要解决我的格式问题的方法是遍历XML文件中的每个段落并查找属性，然后钻取该元素并检查是否需要修改现有的边距条目或添加新的边距条目。我的目标是每个段落元素都有一个包含文档默认边距参数的部分条目。这应该可以缓解格式问题。我似乎无法让它工作。我尝试了几种不同的方式来改变XML文件无济于事...以编程方式在docx文件中的每个段落上更改页边距
当前代码块我工作情况如下，并在进展中的工作，所以一些代码可能无法正常工作：
Dim DocOutput As New WmlDocument(WP_OUTPUT)
Using docStream As New OpenXmlMemoryStreamDocument(DocOutput)
Using wpSource As WordprocessingDocument = docStream.GetWordprocessingDocument()
Dim flag As Boolean
Dim Section As New SectionProperties
Dim Margin As New PageMargin
Margin.Top = 720
Margin.Right = 360
Margin.Bottom = 2347
Margin.Left = 1526
Margin.Header = 432
Margin.Footer = 432
RevisionAccepter.AcceptRevisions(wpSource)
Dim root As XElement = wpSource.MainDocumentPart.GetXDocument.Root
Dim body As XElement = root.LogicalChildrenContent.First
For Each blockLevelContentElement As XElement In body.LogicalChildrenContent()
If blockLevelContentElement.Name = W.p Then
For Each Paragraph As XElement In blockLevelContentElement.Elements()
If Paragraph.Name = W.pPr Then
For Each ParagraphProp As XElement In Paragraph.Elements()
flag = False
If ParagraphProp.Name = W.sectPr Then
For Each SectionProp As XElement In ParagraphProp.Elements()
If SectionProp.Name = W.pgMar Then
SectionProp.SetAttributeValue(W.top, Margin.Top)
SectionProp.SetAttributeValue(W.right, Margin.Right)
SectionProp.SetAttributeValue(W.bottom, Margin.Bottom)
SectionProp.SetAttributeValue(W.left, Margin.Left)
SectionProp.SetAttributeValue(W.header, Margin.Header)
SectionProp.SetAttributeValue(W.footer, Margin.Footer)
flag = True
End If
Next
If flag = False Then
ParagraphProp.SetElementValue(W.sectPr, Margin)
flag = True
End If
End If
Next
If Not flag Then
Paragraph.Add(Section.AppendChild(Margin.CloneNode(False)))
End If
End If
Next
End If
Next
End Using
Dim sources As New List(Of Source)
Dim WmlHolder As New WmlDocument(docStream.GetModifiedWmlDocument)
sources.Add(New Source(WmlHolder, True))
DocumentBuilder.BuildDocument(sources, WP_TEMP)
End Using
我在做什么错当我试图写入正确的值到DOCX文件？我一直在为此挣扎大约4天。有没有可能是我需要与之合作的另一种类型的对象？
UPDATE： 我想通了......我用错了对象模型
此代码的工作完美
