[erlang-questions] xmerl question

Hi,

I am not getting a match correct...

For the #xmlElement like:

<matchup kickoff="1189125000" gameSecondsRemaining="3600">
  <team id="NOS" isHome="0" score=""/>
  <team id="IND" isHome="1" score=""/>
</matchup>

I'm trying to parse it with:

parse_matchup(Matchup) ->
    #xmlElement{attributes=Attribs, content=Content} = Matchup,
    [ #xmlAttribute{name=kickoff, value=Kickoff} ] = Attribs,
    Kickoff.


I'm getting a badmatch [1] when I try to get the value of the 'kickoff'
attribute.  Any idea what I'm doing wrong?

I used

Matchups = [parse_matchup(M) || M <- xmerl_xpath:string("//matchup", Xml)],

to send Matchup to the fn, but I didn't want to keep using xpath on each
attrib and child node, because of efficiency.  Should I not worry about
that?

Cheers,
BA
