Re: [xsl] multiple paths in the "use" in key....I'm getting

Christian,

In XSLT, "and" is a Boolean operator, returning "true" or "false" depending
on the values returned by the operands, when cast to Boolean. This isn't
going to be very useful for defining keys, most of the time.

What you are looking for is probably the "|" operator, which performs a
union of two node-sets. So "blue | green" is the set of all "blue" element
children of the context with all "green" element children.

These are commonly confused because "|" often translates colloquially as
"or" or "and", as in match="blue|green", which matches blue elements, and
also matches green elements, since the elements it matches are all members
of the union set "blue|green" (blue and green children of something). So we
say it "matches blue or green", which is not at all the same thing as XPath
"blue or green", which returns true if one of "blue" or "green" tests true.
Similarly, select="blue|green" selects all the blue children and all the
green children, in a single set.

I hope this helps,
Wendell

And I'm sure the solution is quite simple.

I want to take the address codes in AddressSpecific: (municipalitycode,
streetcode,
streetbuildingIdentifier)
and look them up in the XIaddressSpecific element AND RETURN THE CORRECT
XIaddressSpecificLabelStructure

How do I do that?

I have been trying using keys, with multiple paths in the "use":

      <xsl:key name="ForwardingAddressPostCodeIdentifier"
match="PostCodeIdentifier" use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/StreetBuildingIdentifier" />
      <xsl:key name="ForwardingAddressDistrictName" match="DistrictName"
use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/dkcc2:StreetBuildingIdentifier" />
      <xsl:key name="ForwardingAddressFloorIdentifier"
match="FloorIdentifier" use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/StreetBuildingIdentifier"/>
      <xsl:key name="ForwardingAddressSuiteIdentifier"
match="SuiteIdentifier" use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/StreetBuildingIdentifier"/>


but the "and" between the paths in the "use" doesn't seem to work. PLEASE
HELP ME! I'm going soon
nuts

on beforehand thanx

          <ForwardingAddressStructure>
             <AddressSpecific>
                        <MunicipalityCode>0840</MunicipalityCode>
                        <StreetCode>3270</StreetCode>

<StreetBuildingIdentifier>135</StreetBuildingIdentifier>
            </AddressSpecific>
         </ForwardingAddressStructure>
