Hi,
I guess this is more of an xpath question than a Kamailio one, so
forgive me. All the same, how does one deal with a document like this
using $xml(...):
<?xml version="1.0" encoding="utf-8" ?>
<sheep>
<lamb>
...
</lamb>
<lamb>
...
</lamb>
</sheep>
Specifically, how do I access the second, third, Nth element with the
same tag, but without knowledge of any unique identifying attributes?
Is there a useful way to iterate through them in Kamailio route script?
I would have thought something like this could work:
$var(i) = 0;
while(defined $xml(x=>xpath:/sheep/lamb[$var(i)])) {
...
$var(i) = $var(i) + 1;
}
However, obviously, that's not it. So what's the right way to do it?
My desire is to buffer data from these nodes into an AVP array. As
you might guess, it's a route set over which I need to serially fork.
Thanks!
