parser error : String not started expecting ' or " in php

Hi I'm trying to convert the XML file into associative array by using the following code

$xmlUrl = '../products.xml';
$xmlStr = file_get_contents($xmlUrl); 
$xmlObj = simplexml_load_string($xmlStr);  print_r ($xmlObj);exit;
$arrXml = objectsIntoArray($xmlObj);

and product.xml containing

<?xml version="1.0" encoding="utf-8"?>
<products>
  <product>
    <sku>p750h3</sku>
    <category>Plans: Vodafone Unlimited Cap</category>
    <price>$0</price>

I am trying to fix this issue whole day and searching solution over the net but i could not get . Please let me know the reason?

This is probably caused by magic_quotes_runtime adding backslashes when you call file_get_contents. Try the following:

$xmlUrl = '../products.xml';
$xmlStr = file_get_contents($xmlUrl); 
if (get_magic_quotes_runtime())
{
    $xmlStr = stripslashes($xmlStr);
}
$xmlObj = simplexml_load_string($xmlStr);  print_r ($xmlObj);exit;
$arrXml = objectsIntoArray($xmlObj);    $xmlStr = file_get_contents($xmlUrl);

Alternatively you could disable magic_quotes_runtime (although this may have effects elsewhere in your script) in your PHP configuration, via .htaccess, or by adding the following near the top of your script:

set_magic_quotes_runtime(false);

Just out of curiosity, why aren't you using simplexml_load_file()?

You should fix your XML string, it's not valid. If you want to keep the XML as is and avoid validation errors, use the 3rd argument of simplexml_load_string() to set the right options, see http://php.net/manual/fr/function.simplexml-load-string.php and http://www.php.net/manual/fr/libxml.constants.php

Btw I don't understand why it shows your XML with escaped quotes, is it escaped in the source file?
