[xsl] for-each issue

["Z W" <mpc8250@xxxxxxxxx>]

Hi

I have a xml input file that contains the following:


<sampleResult timeStamp="1191576904342" dataType="text"
threadName="9-1" label="Client responds " time="930"
responseMessage="OK" responseCode="200"
success="true"><assertionResult failureMessage="" error="false"
failure="false"/></sampleResult>
<sampleResult timeStamp="1191575818602" dataType="text"
threadName="-9" label="Notification Receiver" time="1087393"
responseMessage="" responseCode="" success="true"/>
<sampleResult timeStamp="1191575818631" dataType="text"
threadName="1-10" label="Notification Receiver" time="1087824"
responseMessage="" responseCode="" success="true"/>
<sampleResult timeStamp="1191576904770" dataType="text"
threadName="1-2" label="Client responds " time="1663"
responseMessage="OK" responseCode="200"
success="true"><assertionResult failureMessage="" error="false"
failure="false"/></sampleResult>
<sampleResult timeStamp="1191576907600" dataType="text"
threadName="1-4" label="Client sends " time="529" responseMessage="OK"
responseCode="200" success="true"><assertionResult failureMessage=""
error="false" failure="false"/></sampleResult>

I'm trying to create a html where I'm only interested in this
label=Client responds.
However I need to loop through all these rows to get other information.
How do I loop through them and store some values into variables and at
the same time not having XSLT complaining that
variables undefined if these variables are put inside the for-each
loop and made to print out outside of the for-each loop ?








Also,

 Warning! A variable with no following sibling instructions has no effect
What does this warning really imply ?
