使用OpenXML（C＃）解析* .docx文档时遇到一个问题。
所以，这是我的步骤：
1.加载* .docx文件
2.接收段落清单
3.在每个段落中查找文本，图像和表格元素
4.为每个text和image元素创建html标签
5.将输出保存为* .html文件
我已经找到了如何在文档中找到图像文件并将其解压缩。 现在还有一步 - 找到文本中的表位置（段落）。
如果有人知道如何使用OpenXML在* .docx文档中找到表格请帮忙。 感谢。
其他： 好吧，可能我不清楚解释我的意思。 如果我们获得段落的内容，您可以找到chield对象作为文本块，图片等。 所以，如果段落包含Run包含Picture它意味着在这个地方放置Word文档放置图像。
我的功能样本：
public static string ParseDocxDocument(string pathToFile)
{
StringBuilder result = new StringBuilder();
WordprocessingDocument wordProcessingDoc = WordprocessingDocument.Open(pathToFile, true);
List<ImagePart> imgPart = wordProcessingDoc.MainDocumentPart.ImageParts.ToList();
IEnumerable<Paragraph> paragraphElement = wordProcessingDoc.MainDocumentPart.Document.Descendants<Paragraph>();
int imgCounter = 0;
foreach (Paragraph par in paragraphElement)
{
//Add new paragraph tag
result.Append("<div style=\"width:100%; text-align:");
//Append anchor style
if (par.ParagraphProperties != null && par.ParagraphProperties.Justification != null)
switch (par.ParagraphProperties.Justification.Val.Value)
{
case JustificationValues.Left:
result.Append("left;");
break;
case JustificationValues.Center:
result.Append("center;");
break;
case JustificationValues.Both:
result.Append("justify;");
break;
case JustificationValues.Right:
default:
result.Append("right;");
break;
}
else
result.Append("left;");
//Append text decoration style
if (par.ParagraphProperties != null && par.ParagraphProperties.ParagraphMarkRunProperties != null && par.ParagraphProperties.ParagraphMarkRunProperties.HasChildren)
foreach (OpenXmlElement chield in par.ParagraphProperties.ParagraphMarkRunProperties.ChildElements)
{
switch (chield.GetType().Name)
{
case "Bold":
result.Append("font-weight:bold;");
break;
case "Underline":
result.Append("text-decoration:underline;");
break;
case "Italic":
result.Append("font-style:italic;");
break;
case "FontSize":
result.Append("font-size:" + ((FontSize)chield).Val.Value + "px;");
break;
default: break;
}
}
result.Append("\">");
//Add image tag
IEnumerable<Run> runs = par.Descendants<Run>();
foreach (Run run in runs)
{
if (run.HasChildren)
{
foreach (OpenXmlElement chield in run.ChildElements.Where(o => o.GetType().Name == "Picture"))
{
result.Append(string.Format("<img style=\"{1}\" src=\"data:image/jpeg;base64,{0}\" />", GetBase64Image(imgPart[imgCounter].GetStream()),
((DocumentFormat.OpenXml.Vml.Shape)chield.ChildElements.Where(o => o.GetType().Name == "Shape").FirstOrDefault()).Style
));
imgCounter++;
}
}
}
//Append inner text
IEnumerable<Text> textElement = par.Descendants<Text>();
if (par.Descendants<Text>().Count() == 0)
result.Append("<br />");
foreach (Text t in textElement)
{
result.Append(t.Text);
}
result.Append("</div>");
result.Append(Environment.NewLine);
}
wordProcessingDoc.Close();
return result.ToString();
}
现在我想在文本中指定表格位置（因为它出现在Word中）。
决赛：
好的，大家，我发现了。在我的示例函数中有一个大错误。我列举了文件Body的Paragraph元素。表与Paragraph处于同一级别，因此函数忽略表。所以我们需要枚举文档Body的元素。
这是我的测试函数，用于从docx生成正确的HTML（它只是测试代码，所以它不干净）

答案 0 :(得分：1)
请尝试以下方法查找文档中的第一个表。
Table table = doc.MainDocumentPart.Document.Body.Elements<Table>().First();
