我正在構建的應用程序爲我工作的公司生成提案文檔。這是一個複製，替換和刪除DOCX文件和XLSX文件的特定部分的複雜系統。我在生成提案的過程中使用XML powertools「DocumentBuilder」來組裝文檔。我遇到的問題如下。由於模板文件的年限以及我必須處理的絕對數量的選項，「文檔」構建器最終忽略了整個文檔長度的一些邊距設置。我想要解決我的格式問題的方法是遍歷XML文件中的每個段落並查找屬性，然後鑽取該元素並檢查是否需要修改現有的邊距條目或添加新的邊距條目。我的目標是每個段落元素都有一個包含文檔默認邊距參數的部分條目。這應該可以緩解格式問題。我似乎無法讓它工作。我嘗試了幾種不同的方式來改變XML文件無濟於事...以編程方式在docx文件中的每個段落上更改頁邊距
當前代碼塊我工作情況如下，並在進展中的工作，所以一些代碼可能無法正常工作：
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
我在做什麼錯當我試圖寫入正確的值到DOCX文件？我一直在爲此掙扎大約4天。有沒有可能是我需要與之合作的另一種類型的對象？
UPDATE： 我想通了......我用錯了對象模型
此代碼的工作完美
