Thanks - using xml_parse_into_struct does make parsing the document much
easier... great suggestion.
What I've ended up with is:
// create parser
$xp = xml_parser_create();
xml_parse_into_struct($xp,$xml,$vals,$index);
xml_parser_free($xp);
$found_domain = 0;
$results = array();
for($ctr=0; $ctr<count($vals); $ctr++) {
switch($vals[$ctr]["tag"]) {
case "DOMAIN":
$found_domain = 1;
break;
case "STATUS":
if ($found_domain == 1) {
array_push($results,$vals[$ctr]["attributes"][CODE]);
}
break;
case "DESCRIPTION":
if ($found_domain == 1)
array_push($results,$vals[$ctr]["value"]);
break;
}
}
echo "Return Status = " . $results[0] . "<BR>\n";
echo "Return Desc = " . $results[1] . "<BR>\n";
print_r($results);
which then gives me (for something similar to the XMLdoc below):
Return Status = 05<BR>
Return Desc = Successfully added,eh?<BR>
Array
(
[0] => some-numeric-code1
[1] => sometext1
[2] =>
[3] =>
[4] =>
[5] => some-numeric-code2
[6] => sometext2
[7] =>
[8] =>
[9] =>
[10] => some-numeric-code3
[11] => sometext3
[12] =>
[13] =>
[14] =>
)
So I know that every grouping of 5 elements within the results array is
associated with a given domain. (The two that are present are what I
want...what are the others - just remnants of the tree traversal??)
A little more fiddling, and I'll be able to pull it all apart as needed.
This will do me for now though...
But of course, my next question has to be.... isnt there an easier way to
extract elements from the XML document?
