Q: xmerl 0.15 xpath fails to match the following - why?

[Reto Kramer]

I'm using xmerl 0.15 and tried out the xpath matcher with the example below.

Unfortunately the xpath does not match and returns an empty list. The same
happens with e.g. /document.

D: {xmlElement,document, ...
    ... the long form of the xml tree ...
X: []
ok

Does anyone have a test-set for xmerl xpath, so I can mimic the successful
use of it?

cheers,

foo2() ->
    D = xmerl_scan:string(string()),
    io:format("D :~p~n",[D]),
    X = xmerl_xpath:string("/document/section/section/table/row", D),
    io:format("X :~p~n",[X]).


string() ->
     "<document title=\"Doc Title\"
          author=\"Ulf Wiger\">
<section heading=\"heading1\">
<P>
This is a paragraph of text.
</P>
<section heading=\"heading2\">
<P>
This is another paragraph.
