Question

Suppose I have this XML:

<?xml version="1.0" encoding="UTF-8"?>
<root xmlns:foo="http://www.foo.com">
    <foo:one>Alpha</foo:one>
    <two foo:Dog="Yorkie">Bravo</two>
    <three>foo:Delta</three>
</root>

If I want to use XPath to find all elements that are in the “http://www.foo.com” namespace (such as the element “one”), I can use this:

//*[namespace-uri()='http://www.foo.com']

If I want to find all elements that have an attribute in that namespace (such as the element “two”), I can use this:

//@*[namespace-uri()='http://www.foo.com']

If I want to find all elements that have a text node in that namespace (such as the element “three”), what XPath can I use?

XPath 1 or 2 allowed. Thanks.

There is no such thing as a namespace on a text node; your three node just contains the text foo:Delta, which has no special meaning in XML. You can find nodes holding text starting with foo: using starts-with:

//*[starts-with(., "foo:")]
