Masking Non-XML sensitive data post logging in xslt - xslt

Question

Can anyone please help me on masking of non-XML input in Datapower.
I am logging the input first in Datapower log store and taking that input to mask, I have written a piece of code which works for XML but not for non-XML,
attaching my input non-XML and code for the reference.
Attached masking file.xsl has two templates, one for non-XML and another for XML. XML is working fine for numeric values and not masking the characters.
Non-XML template is called but not doing masking.(I can see in system logs it is being called)
The control given to masking template is given by a different log.xml file attached.
Quick response is appreciated.
Thanks,
Anuj

Perhaps you could use this technote to wrap the non-xml in XML and then use your XSLT
http://www-01.ibm.com/support/docview.wss?uid=swg21321379
Relevant portion:
Transforming raw text to pseudo-XML:
This example will take the following text as input:
some text here
and here is some more
and some more
and some more
and wait, some more here
Steps to Create:
1.Create a Transform action in the service that will be receiving non-XML requests.
2.Select "Use XSLT specified in this action on a non-XML message" to specify that this is a Binary Transform.
3.Upload the following style sheet as the Processing Control File.
4.Click Done, and Apply all windows.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dp="http://www.datapower.com/extensions"
version="1.0">
<dp:input-mapping href="sample.ffd" type="ffd"/>
<!-- This stylesheet copies the input to the output -->
<xsl:output method="xml"/>
<xsl:template match="/">
<xsl:value-of select="sampleFile/sampleTag" disable-output-escaping="yes" />
</xsl:template>
</xsl:stylesheet>
Upload the following FFD file into the local://sample.ffd directory from the File Manager.
<File name="sampleFile">
<!-- capture all data into this tag -->
<Field name="sampleTag" />
</File>
Sending the sample input above will result in the following output
<?xml version="1.0" encoding="utf-8"?>
<sampleFile>
<sampleTag>
some text here
and here is some more
and some more
and some more
and wait, some
</sampleTag>
</sampleFile>
