Hi,
In one of the scenario i have to read mqrfh2 header and take the value of of one the name value pair of usr folder and need to set in the context variables.
I have an mpg defined as MQ FSH and backend also mq. The client drops the msg with rfh2 header. My MQ FSH read the msg and parses the rfh2 header and takes the 'transId' of the usr folder and sets it in the context.

The configuration i have done in the MQ FSH is


Quote:

I have turned on Parse Header to on
Exclude Message Headers -- MQRFH and MQRFH2
content type-- MQRFH2
xpath-- /*[local-name()='MQRFH2']/*[local-name()='NameValueData']/*[local-name()='NameValue']/*[local-name()='usr']/*[local-name()='TransId']



In my processing rule, i have written the xsl, which will take this transId and sets into context variable.
Code:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:dp="http://www.datapower.com/extensions"
  xmlns:date="http://exslt.org/dates-and-times"
  xmlns:exsl="http://exslt.org/common"
  xmlns:dpfunc="http://www.datapower.com/extensions/functions"
  xmlns:dpconfig="http://www.datapower.com/param/config"
  extension-element-prefixes="dp date exsl dpfunc dpconfig"
  exclude-result-prefixes="dp date exsl dpfunc dpconfig">
   <xsl:template match="/">
      <!-- get the MQRFH2 header from the request message -->
      <xsl:variable name="entries"
         select="dp:request-header(MQRFH2)" />
      <!-- parse into a usable nodeset -->
      <xsl:variable name="header" select="dp:parse($entries)" />
      <!-- store the desired values in a variable available for later -->
      <xsl:variable name="transId" select="$header//NameValueData/NameValue/usr/TransId" />
      <xsl:variable name="Format" select="$header//Format" />
      <dp:set-variable name="'var://context/txn/msg-transid'"
         value="$transId" />

   </xsl:template>
</xsl:stylesheet>





I am getting error at dp:parse($entries).

var://local/_extension/error string 'dp:parse() error: Incomplete markup or missing document element at offset 0 of *dp:parse*'


Does any one have any clue why its through error?

Thanks,
SRK

I got the fix for this.
i was trying to
Quote:

content type-- MQRFH2
xpath-- /*[local-name()='MQRFH2']/*[local-name()='NameValueData']/*[local-name()='NameValue']/*[local-name()='usr']/*[local-name()='TransId']

this is fixing my issue. This xpath expression is setting the TransId value in the service variablevar://service/original-content-type
i am justing reading this one and set it into the context variable.


thanks
SRK
