MK:
Thanks for the eval hint, I had figured that.
key match="field" use="concat(../../@rsname, '#', ., '#', @fieldname)"
and then replace the above expression with
key('k', concat('ABC', '#', 'xxx', '#', 'DEF'))
Errr... I'm not sure what you concat and key solution you provided
accomplishes. What I was hoping to accomplish with:
/root/recordset[(_at_)rsName='ABC']/record[field[(_at_)fieldname='DEF'] =
'xxx']
ABC, supplied rsName value to match. So, rsName = "membership" or
rsName="student" or rsName = "ABC".
Same with DEF: match fieldname that is "DEF", or feidlname that is
"Last_Name" or fieldname that is "ZipCode".
Same with "xxx", so now you have (spoken in english) and using
membership and Last_Name to replace ABC and DEF respectfully the
following:
"Return the record from the recordset who's name is "memberships" and
who's field "Last_Name" = "Smith".
I hope that clarifies things better.

Hello,
Is it possible to invoke a select or test or other xpath query from
the value found within a variable or param?
You need an extension such as saxon:evaluate() or dyn:evaluate in EXSLT.
- ALSO -
How can you create a key for the following, where "ABC" and "XYZ" and
"xxx" are all the values I'd like to supply to the key for matching:
/root/recordset[(_at_)rsName='ABC']/record[field[(_at_)fieldname='DEF'] =
'xxx']
I'm not sure I understand the question. But you can define a key
key match="field" use="concat(../../@rsname, '#', ., '#', @fieldname)"
and then replace the above expression with
key('k', concat('ABC', '#', 'xxx', '#', 'DEF'))
