Description Jamie Norrish 2005-08-24 08:54:41 UTC 
Version details: Debian package version: 2.6.20-1
Distribution/Version: Debian GNU/Linux unstable

Using the Python bindings, xml:id attribute values are not considered to be IDs
for the purposes of (at least) the XPath id function.

To reproduce, add an xml:id attribute to an element in an existing doc:

    ns = root.searchNsByHref(doc, 'http://www.w3.org/XML/1998/namespace')
    prop = elem.setNsProp(ns, 'id', 'b')

Then try finding that element using the XPath id function:

    ctxt = doc.xpathNewContext()
    print bool(ctxt.xpathEval('id("b")'))

And False is printed.

The expected result is that it finds the element and prints True.

The potentially useful doc.addID(None, 'b', prop) doesn't work because addID is
not generated in the Python bindings.
