      <p> THIS TEXT</p>
    </html>
  </my:ProjectDescription>

</my:myFields>

我可以使用以下代码访问标记内的字段： VendorName ＆ AssignedTo

XmlNodeList nodelist1 = xml.GetElementsByTagName("my:myFields");
foreach (XmlNode node in nodelist1)
            text_name = node["my:VendorName"].InnerText;

但是我无法使用以下命令访问ProjectDescription标记内的内部文本，即“ THIS TEXT”

XmlNodeList nodelist1 = xml.GetElementsByTagName("my:myFields/my:ProjectDescription/html");
foreach (XmlNode node in nodelist1)
                text1 = node["p"].InnerText;

在调试模式下运行时，我在nodelist1中得到NULL。

请给我建议一种方法。

Answer 1

XmlNamespaceManager nsm = new XmlNamespaceManager(xml.NameTable);
nsm.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2013-01-09T15:23:27");
nsm.AddNamespace("x", "http://www.w3.org/1999/xhtml");

XmlNodeList nodelist1 = xml.SelectNodes("my:myFields/my:ProjectDescription/x:html",nsm);
foreach (XmlNode node in nodelist1)
    Console.WriteLine(node["p"].InnerText);

Answer 2

这有效：

XmlNodeList nodelist1 = xml.SelectNodes("my:myFields/my:ProjectDescription");
            foreach (XmlNode node in nodelist1)
            {
                text1 = node["html"].InnerText;
            }

它将tag.innerText转换为段落格式，即使在字符串text1中也是如此。 您可以从那里修剪它。

Answer 3

我使用System.Xml.Linq.XDocument和XPath创建了一个解决方案。 我认为您可以最好地使用XPath。 它解释了我认为的名称空间问题。

XPath的：

using System.Xml.XPath;

var document = System.Xml.Linq.XDocument.Load(@"D:\test.xml");
var namespaceManager = new System.Xml.XmlNamespaceManager(new System.Xml.NameTable());
namespaceManager.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2013-01-09T15:23:27");
namespaceManager.AddNamespace("html", "http://www.w3.org/1999/xhtml");
var pValue = document.XPathSelectElement("/my:myFields/my:ProjectDescription/html:html/html:p", namespaceManager).Value;

的XDocument：

var xml = System.Xml.Linq.XDocument.Load(@"D:\test.xml");

var myNamespace = "http://schemas.microsoft.com/office/infopath/2003/myXSD/2013-01-09T15:23:27";
var htmlNamespace = "http://www.w3.org/1999/xhtml";

var myFields = xml.Element(System.Xml.Linq.XName.Get("myFields", myNamespace));
var projectDescription = myFields.Element(System.Xml.Linq.XName.Get("ProjectDescription", myNamespace));
var htmlTag = projectDescription.Element(System.Xml.Linq.XName.Get("html", htmlNamespace));
var pTag = htmlTag.Element(System.Xml.Linq.XName.Get("p", htmlNamespace));

var pValue = pTag.Value;
