<xsl:variable name="hasContracts" select="
count(/Output[$branding = 'ABC']/Contracts/Contract[substring(ContractId,
1,1)='Q']) > 0
or
boolean(/Output[$branding != 'ABC']/Contracts/Contract)
"/>
although since a test of count() > 0 is just testing if the node set is
non empty, and boolean() does the same, and substring 1,1 is the start
of the string, this can be simplified to
<xsl:variable name="hasContracts" select="
/Output[$branding = 'ABC']/Contracts/Contract[starts-with(ContractId,'Q')]
or
/Output[$branding != 'ABC']/Contracts/Contract
"/>
which makes it clearer that it can be further simplified to
<xsl:variable name="hasContracts" select="
boolean(/Output/Contracts/Contract[($branding = 'ABC' and
starts-with(ContractId,'Q')) or not($branding = 'ABC')])
"/>
which is probably closer to the original description of the problem.
