I have an XML file that looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<lastmod>10:58:33</lastmod>
<stat>
<name>Bookings</name>
<type>Int</type>
<value>28</value>
</stat>
<stat>
<name>Avg Pick</name>
<type>Float</type>
<value>8.5</value>
</stat>
</dataset>The XML file is produced by a crystal report. As such there are some lines of whitespace at the top of the file which can't be avoided. If I open the file in IE, for example, it picks it up fine.
However, when I try this
<?php
$xml = array();
function myRecordHandler($record) {
global $xml;
$xml[] = $record;
}
$result = MagicParser_parse("test.xml","myRecordHandler");
if (!$result) {
print MagicParser_getErrorMessage();
}
print_r($xml);
?>
I get
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.

Have tried using autodetection but "XML/Dataset/" doesn't seem to work.
Help!
Hi David,
Unfortunately that doesn't work. It just returns:
Array ( )
Sorry about that - i've been able to replicate the problem now. I'll investigate the circumstances there, but in the mean time you should be able to use the createFile function to create a version of the file with white space stripped. The following code should work:
<?php
require("MagicParser.php");
$stats = array();
function myRecordHandler($record) {
global $stats;
$stats[] = $record;
}
// read XML into a string
$fp = fopen("test.xml","r");
while(!feof($fp)) $xml .= fread($fp,1024);
fclose($fp);
// remove white space
$xml = trim($xml);
// parse using temporary file API
$temp = MagicParser_createFile($xml);
$result = MagicParser_parse($temp,"myRecordHandler","xml|DATASET/STAT/");
if (!$result) {
print MagicParser_getErrorMessage();
}
print_r($stats);
?>
That works, thanks. But of course it would be better and quicker not to have to trim the file--can you let me know what you find as to why it doesn't work?
Cheers,
Jay
David,
Any luck yet in determining / fixing the root cause of the problem?
Cheers,
Jay
David,
How about some follow up here please???

Hello Jay,
My apologies for overlooking this thread.
As the file is technically not valid XML it will require an update to the script in order trim white space where an XML format string is provided. For performance reasons I would rather not incorporate this into the distribution, but I would be happy to create a customised version that should remove the need to download the file to your server and perform the trim at the start of the parsing process.
I'll drop you an email shortly with the new version.
Cheers,
David.
Hello Jay,
I have actually decided to incorporate leading white space removal into the script, so you can now download the latest version to avoid having to create the temporary file.
The example from this thread would now be as follows:
<?php
require("MagicParser.php");
$stats = array();
function myRecordHandler($record) {
global $stats;
$stats[] = $record;
}
$result = MagicParser_parse("test.xml","myRecordHandler","xml|DATASET/STAT/");
if (!$result) {
print MagicParser_getErrorMessage();
}
print_r($stats);
?>
Hope this helps,
Regards,
David.
Hi There,
White space will cause autodetection to fail; but the parse should still work with the correct format string, which in the case of your example XML should be:
xml|DATASET/STAT/Secondly, i'm not sure why your example script is being interpretted by the browser as XML; as you are not creating XML headers at all.
However, that said; the following code should work; and your print_r() statement at the end should print out an array of each STAT from the XML file...
<?php$stats = array();
function myRecordHandler($record) {
global $stats;
$stats[] = $record;
}
$result = MagicParser_parse("test.xml","myRecordHandler","xml|DATASET/STAT/");
if (!$result) {
print MagicParser_getErrorMessage();
}
print_r($stats);
?>
Let me know if that code works as it stands..
Cheers,
David.
