Error loading stylesheet: An unknown error has occurred (805303f4)?
<p>I'm trying to generate a shipping label from an XML response file I received from the shipper's API, however, when I try to access the XML via my browser I get this <strong>Error loading stylesheet: An unknown error has occurred (805303f4)</strong> error.</p>

<p><strong>XML Response File:</strong></p>

<pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?&gt;
&lt;?xml-stylesheet href="http://shippers-website.com/label.xsl" type="text/xsl"?&gt;
</code></pre>

<p><strong>XSL File:</strong></p>

<pre><code>&lt;?xml version='1.0'?&gt;
&lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/TR/WD-xsl"&gt;
</code></pre>

<p>I then tried to open this XML file locally on my PC and I saved a local copy of the XML and XSL files, but when I did this I would get this <strong>Error loading stylesheet: Parsing an XSLT stylesheet failed.</strong> error.  </p>

<p>I then changed the XSL file namespace from <strong><a href="http://www.w3.org/TR/WD-xsl" rel="nofollow">http://www.w3.org/TR/WD-xsl</a></strong> to <strong><a href="http://www.w3.org/1999/XSL/Transform" rel="nofollow">http://www.w3.org/1999/XSL/Transform</a></strong> and that seemed to work on my local XML copy; which is a good sign, however, I need this to work properly with the URL from my shipper's website that is listed in the XML file (e.g. <strong><a href="http://shippers-website.com/label.xsl" rel="nofollow">http://shippers-website.com/label.xsl</a></strong>).</p>

<p>They tell me that this same XML type response file works for their other customers, so I'm not sure why it's not working for me.</p>

<p>Does anyone have an idea of why I'm getting this error when I call the XML file when it's pointing to my shipper's server XSL file (e.g. <strong><a href="http://shippers-website.com/label.xsl" rel="nofollow">http://shippers-website.com/label.xsl</a></strong>)?</p>

<p>Thank you!</p>
