Hi Folks,
The following XPath expression returns all XML Schema element
declarations with @type equal to xs:string:
//xs:element[@type = 'xs:string']
However, that XPath assumes the schema file is written with a
namespace prefix, like this:
<xs:element name="Test" type="xs:string" />
But the schema file could have been written like this:
<element name="Test" type="string" />
There are two issues here. The first is matching the element called
'element' and your XPath expression will work fine there, assuming
you've bound the prefix "xs" to the XML Schema namespace URI and that
the same namespace name is the default namespace for the prefix-less
Schema document.
The second issues is matching "string" or xs:string". We know that it's
a QName and must have zero or one colon, so
@type = "string" or substring-after(@type, ":") = "string"
would work.
