XSL Transformation issue for an XML - xslt

Question

I am accessing a WebService which give me a valid response. While parsing the response using an XSL Transformation, I am getting SAXParseException. If I tested in the online tools such as freeformatter.com, I am getting a proper parsing without any issues. Any help is greatly appreciated.
The response I have received from the WebService is below
<?xml version="1.0"?><message channel-id="10a60e45-65d4-40c0-826f-1a91d2135da0">
<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<ns:ITSPResponse xmlns:ns="urn:PegaRULES:SOAP:BNYMDataITSPTest:Services">
<Output>Test IT Service Portal - 1</Output>
</ns:ITSPResponse>
</soap:Body>
</soap:Envelope>
</message>
I am trying to parse the response using XSL Transformation; but receiving an exception. The XSL I am using
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns="urn:PegaRULES:SOAP:BNYMDataITSPTest:Services">
<xsl:template match="/">
<message>
<xsl:attribute name="channel-id">

</xsl:attribute>
<send-parameters>
<agent-parameter>

<value> <xsl:value-of select="//*[local-name()='Output']" /> </value>
</agent-parameter>
</send-parameters>
</message>
</xsl:template>
</xsl:stylesheet>
The exception I am getting is

I am not sure whether I am missing anything anywhere?

Answer 1

There are two possibilities: Either the document you're reading is ending unexpectedly (and is not well formed), or the stylesheet is ending unexpectedly (and is not well formed). The stylesheet is itself an XML document, after all, and can produce the same exceptions. Looking at the call stack for the exception may help you determine which is true. Running the program under a debugger might also help, by letting you see which URI the parser was trying to read from when it failed.
Or the exception could be coming from parsing some other part of your program and an XML document unrelated to this transformation. Again, look at the exception's call stack, or fire up the program under a debugger, to see what document is causing trouble.
If the parser tells you a file is ending prematurely, it's ending prematurely.
