xpath question for reading attribute value namespace-unaware

[manuel aldana]

hi i want to read an attribute value ignoring bound namespace (namespace declarations are omitted in following):

<xml bla="asdf"/>
<xml ns1:bla="asdf"/>

the retrieval i am doing with xpath.

i tried //*[@attributeName] but this would only work with the unqualified (<xml bla="asdf"/>) version. is there a wildcard version which ignores the namespace prefix of the attribute?
i do not want to use the local-name() function for i don't know the element the attribute is contained in.

thanks for your help!

a colleague was quicker than you ;)

//*/@*[local-name()='bla'] made the trick
