----------------------------------------------------------------
Simplifying this down drastically, renaming it {*}jalan-xira-2474.{*}{*}, and
using my *identitext.xsl{*} transformation to roughly dump (non-indented)
content of a node in the messages.
The first computed path they try to execute expands to:
{code:java}
"document('jira-xalanj-2474.xml')/*/NetworkElement[Name='FTMYFLXABB0' and
Description='Ascend CBX 500' and Id='1000000010' and CreationTime='' and
LastUpdatedTime='' and Enabled='EnableType.Enabled' and ManagementAddress=''
and LastDiscovered='2002-05-11 21:21:56.0' and FirstDiscoveryFailure='' and
LastDiscoveryFailure='' and NumDiscoveryFailures='0' and
NemClass='com.comanage.truesource.nem.naviscore.NavisCoreNem' and
ContactAddress='Ipv4Address:172.20.254.1' and Vendor='Lucent' and Model='CBX
500' and HardwareVersion='03' and SoftwareVersion='04.02.00.00' and
SerialNumber='' and Supplier='' and PartNumber='' and Clei='' and Label='' and
Credibility='CredibilityLevel.Medium' and SlotCount='4' and
AvailableSlotCount='-1' and HostAgent[@xlink:href='nil'] and
HostSystem[@xlink:href='nil'] and Host[@xlink:href='nil']]"
{code}
If I invoke the path "normally" from the stylesheet, it returns the correct
node.

So it looks like the root problem is either that *xalan:evaluate()* isn't
working at all for a string supplied in a variable, or it isn't supporting
*document()* within that string.
Tried removing the *string()* call, made no difference.
But this is now simple enough that it's worth considering debugging into.

But this is now simple enough that it's worth considering debugging into.
NOTE: It's also simple enough that I can go back to just outputting the results
rather than using my *identitext* kluge to convert them to text and put them
into messages. I'll do that and post the simplified testcase.

> Affects Versions: 2.7.1
> Environment: Windows, using command line transform of xalan.

> where as the same code works with 2.6.0.
> Info : document and evaluate functions are used in xslt and there were other
> slightly inconsistent behaviour also for 2 versions in terms of syntax and
> all. and xlink:href is getting nil values in 2.7.1
> document result contained by path variable line 93 - transform.xsl is the one
