You just caught me! I'll answer now but it may be tomorrow before I can follow up if necessary...
What you need to do is parse your XML at a higher level to extract any "header" information you want that is higher up the tree than the repeating records that you are primarily interested in before parsing the repeated records. Because this involves parsing twice, it's more efficient to load your XML into a string rather than read the file / URL twice.
To extract TotalPages before displaying each Result, you would do something like this:
<?php require("MagicParser.php"); function myHeaderRecordHandler($record) { global $TotalPages; $TotalPages = $record["TOTALPAGES"]; } function myRecordHandler($record) { // display each record here } $xml = file_get_contents("results.xml"); // could be URL MagicParser_parse("string://".$xml,"myHeaderRecordHandler","xml|RESULTS/"); print "Total Pages:".$TotalPages; MagicParser_parse("string://".$xml,"myRecordHandler","xml|RESULTS/RESULT/"); ?>
Hi Thomas,

What you need to do is parse your XML at a higher level to extract any "header" information you want that is higher up the tree than the repeating records that you are primarily interested in before parsing the repeated records. Because this involves parsing twice, it's more efficient to load your XML into a string rather than read the file / URL twice.
As an example, consider the following XML:
<Results><Query>Bar</Query>
<TotalPages>160</TotalPages>
<CurrentPage>1</CurrentPage>
<Result>
<Foo>Bar1</Foo>
</Result>
<Result>
<Foo>Bar2</Foo>
</Result>
<Result>
<Foo>Bar3</Foo>
</Result>
</Results>
To extract TotalPages before displaying each Result, you would do something like this:
<?phprequire("MagicParser.php");
function myHeaderRecordHandler($record)
{
global $TotalPages;
$TotalPages = $record["TOTALPAGES"];
}
function myRecordHandler($record)
{
// display each record here
}
$xml = file_get_contents("results.xml"); // could be URL
MagicParser_parse("string://".$xml,"myHeaderRecordHandler","xml|RESULTS/");
print "Total Pages:".$TotalPages;
MagicParser_parse("string://".$xml,"myRecordHandler","xml|RESULTS/RESULT/");
?>
Hope this helps!
Cheers,
David.
