Read again :)

I can't see an ugly XPath with all that local-name() stuff.

In your case it would be:

xPath = "//*[local-name()=ParentPrescription]"
   + "/*[local-name()=pertinentInformation1]"
   + "/*[local-name()=pertinentPrescription]"
   + "/*[local-name()=author]"
   + "/*[local-name()=signatureText]"
   + "/*[local-name()=Signature]";

HTH,

Heiner

P.S.: That's how I generated most of it in a u*ix shell:
echo ParentPrescription/pertinentInformation1/pertinentPrescription\
/author/signatureText/Signature | \
awk '\
   BEGIN { RS="/" } \
   { printf "\n  + \"/*[local-name()=%c%s%c]\"",39,$1,39} \
   END { printf ";\n"}'
