Xml – Exclude specific tag from selection in XPath

xmlxpath

I know this is a simple question, but I can't figure it out.
Consider the following simple XML document:

<root>
  <a></a>
  <b></b>
  <c></c>
  <a></a>
  <d></d>
  <e></e>
  <a></a>
  <a></a>
</root>

What's the best way to select the nodes <b> through <e> using XPath?

I'm looking for something like

/root/*[not(a)]

(which does not do the trick)

Best Answer

/root/*[not(self::a)]

C# – Using Xpath With Default Namespace in C#

First - you don't need a navigator; SelectNodes / SelectSingleNode should suffice.

You may, however, need a namespace-manager - for example:

XmlElement el = ...; //TODO
XmlNamespaceManager nsmgr = new XmlNamespaceManager(
    el.OwnerDocument.NameTable);
nsmgr.AddNamespace("x", el.OwnerDocument.DocumentElement.NamespaceURI);
var nodes = el.SelectNodes(@"/x:outerelement/x:innerelement", nsmgr);

XPath: How to select elements based on their value

The condition below:

//Element[@attribute1="abc" and @attribute2="xyz" and Data]

checks for the existence of the element Data within Element and not for element value Data.

Instead you can use

//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]
