我正在尝试连接到Microsoft Word文档(.docx)以读取位于.docx中的表中的值。我正在使用Open-XML SDK 2.0建立与.docx文件的连接。在寻找示例和想法之后到目前为止,我有了这个,
public static string TextFromWord(string file)
{
const string wordmlNamespace = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
StringBuilder textBuilder = new StringBuilder();
using (WordprocessingDocument wDoc = WordprocessingDocument.Open(filename,false))
{
//Manage namespaces to perform Xpath queries
NameTable nt = new NameTable();
XmlNamespaceManager nsManger = new XmlNamespaceManger(nt);
nsManager.AddNamespace("w", wordmlNamespace);
//Get the document part from the package.
//Load the XML in the document part into an XmlDocument instance.
XmlDocument xdoc = new XmlDocument(nt);
xdoc.Load(wdDoc.MainDocumentPart.GetStream());
XmlNodeList paragraphNodes = xdoc.SelectNodes("//w:p", nsManager);
foreach (XmlNode paragraphNode in paragraphNodes)
{
XmlNodeList textNodes = paragraphNode.SelectNodes(".//w:t", nsmanager);
foreach (System.Xml.XmlNode textNode in textNodes)
{
textBuilder.Append(textNode.InnerText);
}
textBuilder.Append(Environment.NewLine);
}
}
return textBuilder.ToString();
}
当.docx中只有文本时,代码可以工作,但当文本在表中时,代码会失败。有没有办法解决这个问题,以便它可以与.docx中的表一起使用?

尝试以下简单的重写方法。它用OpenXML elements (Document, Body, Paragraph, Table, Row, Cell, Descendants, etc)替换您的System.XML调用和命名空间项。请install and use the OpenXML 2.5 SDK。
public static string TextFromWord(string filename)
{
StringBuilder textBuilder = new StringBuilder();
using (WordprocessingDocument wDoc = WordprocessingDocument.Open(filename, false))
{
var parts = wDoc.MainDocumentPart.Document.Descendants().FirstOrDefault();
if (parts != null)
{
foreach (var node in parts.ChildElements)
{
if(node is Paragraph)
{
ProcessParagraph((Paragraph)node, textBuilder);
textBuilder.AppendLine("");
}
if (node is Table)
{
ProcessTable((Table)node, textBuilder);
}
}
}
}
return textBuilder.ToString();
}
private static void ProcessTable(Table node, StringBuilder textBuilder)
{
foreach (var row in node.Descendants<TableRow>())
{
textBuilder.Append("| ");
foreach (var cell in row.Descendants<TableCell>())
{
foreach (var para in cell.Descendants<Paragraph>())
{
ProcessParagraph(para, textBuilder);
}
textBuilder.Append(" | ");
}
textBuilder.AppendLine("");
}
}
private static void ProcessParagraph(Paragraph node, StringBuilder textBuilder)
{
foreach(var text in node.Descendants<Text>())
{
textBuilder.Append(text.InnerText);
}
}
注意 - 此代码仅适用于由段落和表格组成的简单Word文档。此代码尚未在复杂的Word文档中进行测试。
使用控制台应用程序中的上述代码处理了以下文档:
这是文本输出:
