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

In that particular instance of xml you have multiple attributes, so the
pattern match would need to be something along the lines of:

[#xmlAttribute{name=kickoff, value=Kickoff}|_] = Attribs,

but be aware this way depends on the kickoff attribute being first in the
element so its still pretty fragile.
