HELP: XML error 4: Out of Memory

[rzazueta]

OK, this thing is driving me insane. I'm running PHP 4.1.1 as a module under Apache 1.3.20 on Windows XP. I'm trying to do some XML Parsing using PHP's XML functions and the expat library presmuably built into my Apache installation. However, every time I try to parse my file, I get the XML error "out of memory".

In php.ini, I increased the memory_limit config from 8M to 16M and the problem persists. Looking at the usage on my machine, there's plenty of memory left over (well over 100M😎 and no apparent memory spike occurs when I run the script. This all leaves me to think there's a config option, possibly for expat, which I'm missing.

Does anyone have any idea why this may be occurring? Any suggestions? My thanks to you in advance!

Thanks!

Here's a bit more info to help you: The file is a VERY small XML file -- about 1k. It contains XHtml plus extra tags and a little PHP (it's actually an HTML template I'm trying to parse).

The code I'm using follows:

function parseFormTemplate($filename) {
	$parser = xml_parser_create();
	xml_set_element_handler($parser, 'startFormPageElement', 'endFormPageElement');
	$fp = fopen($filename, "r") or die("Could not open ".$filename);
	while($data = fread($fp, filesize($filename))) {
		xml_parse($parser, $data, feof($fp));
	}
	if(xml_get_error_code($parser)) {
		echo("An XML error occurred: ".xml_get_error_code($parser).": ".xml_error_string($parser)." Line: ".xml_get_current_line_number($parser)." Column: ".xml_get_current_column_number($parser)."<br />");
	}
	xml_parser_free($parser);
}

function startFormPageElement($parser, $name, $attr) {
	if(strtolower($name) == 'content') {
		if(($attrName = $attr["NAME"]) && ($attrType = $attr["TYPE"])) {
			switch (strtolower($attrType)) {
				case 'text':
					$inputType = "<input type=text name=".$attrName." size=25>";
					break;
				case 'textarea':
					$inputType = "<input type=textarea name=".$attrName." size=25>";
					break;
				case 'image':
					$inputType = "Image Url: <input type=text name=".$attrName."-image size=50>&nbsp;&nbsp;&nbsp;Link Url: <input type=text name=".$attrName."-link size=50>";
					break;
				case 'link':
					$inputType = "<br /><textarea name=".$attrName." cols=50 rows=25></textarea>";
					break;
				case 'include' :
					$inputType = "<?php listIncludes(); ?>";
					break;
				default :
					$inputType = "An error occured while parsing this value.";
					break;
			}

			echo($attrName.":&nbsp;".$attrName);
		} else {
			echo("Error parsing XML Doc -- no attributes");
		}
	} else {
		echo("Not content");
	}
}

function endFormPageElement($parser, $name, $attr) {
	//Nothing to do here
}

Hope that helps. Thanks again!

I haven't had that error... but I've been using xml on php 4.0.0 and 4.0.6 and get goofy errors with each setup....leaving me to think that...php isn't ready for xml 🙁
