[Xmlstar-devel] c14n xpath

[Keith B. <KSB...@lb...>]

Hello,

Wonderfull little tool this is, though I've a questions about c14n and 
xpath.

I'm trying to work through the example of exclusinve c14n from the 
exc-xmlc14n spec and xml doesn't seem to like the xpath expression. 
Specifically:

$ cat doc1.xml
<n0:pdu xmlns:n0='http://a.example.com'>
   <n1:elem1 xmlns:n1='http://b.example'>
     content
   </n1:elem1>
</n0:pdu>

$ xml c14n --without-comments  doc1.xml '(//. | //@* | 
//namespace::*)[ancestor-or-self::n1:elem1]'
warning: failed to load external entity 
"(//.%20%7C%20//@*%20%7C%20//namespace%3A%3A*)%5Bancestor-or-self%3A%3An1%3Aelem1%5D"
Error: unable to parse file "(//. | //@* | 
//namespace::*)[ancestor-or-self::n1:elem1]"
Error: unable to evaluate xpath expression

Am I doing something wrong here?

Thanks,
ksb
