Problems with Xpath when adding namespace

[David Williams]

I have a simple XML file that I have been using:

<component name="test">
<class name="class"/>
<component>

Up till now, the Xpath of "//component[@name="test"]/class[@name="class"]"
worked well to select the <class> tag.

Recently we added a namespace to the <component> tag:

<component xmlns=http://tempuri.org/test.xsd name="test">

Now, the Xpath no longer works from with in VB.NET. However, it is fine
when I check it via XMPSpy.

I tried adding a XMLNamespaceMan ger to the SelectSingleNod e, but to no
avail. any suggestions?

TIA

Every one hits this problem at least once.

You can change you XPath to:
1.
"//*[local-name()='compone nt'][@name="test"]/*[local-name()='class'][@name="
class"]"
or
2. "//test:component[@name="test"]/test:class[@name="class"]"
XmlNamespaceMan ager nsman = new XmlNamespaceMan ager();
nsman.AddNamesp ace("test", http://tempuri.org/test.xsd);

You'll find an example of using namespaces (default and local) and XPath
together in .NET at the following URL:
