XmlNode.InnerText

We have XML like so:

<Example>
  <Node>Some text here
    <ChildNode>Child 1</ChildNode>
    <ChildNode>Child 2</ChildNode>
  </Node>
</Example>

We are using XmlDocument to parse this.

When we have the XmlNode of the "Node" element, XmlNode.InnerText returns us this:

"Some text hereChild 1Child2"

How can we get the inner text of the Node element without the child nodes' inner text? We don开发者_运维百科't really want to use any RegEx or string splitting to accomplish this.

Note: We also don't want to switch to using a different set of classes to parse this XML, it would be too much of a code change.

var doc = new XmlDocument();
doc.LoadXml(xml);
var text = doc.SelectSingleNode("Example/Node/text()").InnerText; // or .Value

returns

"Some text here\r\n    "

and text.Trim() returns

"Some text here"

How about:

XmlDocument d=new XmlDocument();
d.LoadXml(@"<Example>
  <Node>Some text here
    <ChildNode>Child 1</ChildNode>
    <ChildNode>Child 2</ChildNode>
  </Node>
</Example>");
var textNodeValues=d.DocumentElement
    .FirstChild
    .ChildNodes
    .Cast<XmlNode>()
    .Where(x=>x.NodeType==XmlNodeType.Text)
    .Select(x=>x.Value);

You can implement like:

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<Example><Node>Some text here<ChildNode>Child 1</ChildNode><ChildNode>Child 2</ChildNode></Node></Example>");
    XmlNode node = doc.SelectSingleNode( "Example/Node" );
    if (node.HasChildNodes)
    {
        string value = node.FirstChild.Value;
    }

To my knowledge, there is no direct way to do that. You'll have to iterate over the child text nodes and build the concatenated text yourself:

using System.Text;
using System.Xml;

public string GetImmediateInnerText(XmlNode node)
{
    StringBuilder builder = new StringBuilder();
    foreach (XmlNode child in node.ChildNodes) {
        if (child.NodeType == XmlNodeType.Text) {
            builder.Append(child.Value);
        }
    }
    return builder.ToString();
}

You can also use the text() XPath expression, as @abatishchev does:

public string GetImmediateInnerText(XmlNode node)
{
    StringBuilder builder = new StringBuilder();
    foreach (XmlNode child in node.SelectNodes("text()")) {
        builder.Append(child.Value);
    }
    return builder.ToString();
}
