RE: Is there a way to tell if a node is an integer?

It's real code, allright. The problem you are experiencing is very likely the result of your using an XSLT 1.0 transformer. XSLT 2.0 opens the door to schema-aware processing. The "xs:" namespace is from XML Schema (http://www.w3.org/2001/XMLSchema). XML Schema makes possible the definition of elements as being of particular data types. If you were using an XSLT 2.0 schema-aware processor and you defined your stylesheet as being an XSLT 2.0 stylesheet, the test would work.

See these links:

Subject:   Is there a way to tell if a node is an integer?

Hi, 

Is there a way to tell if a node is an integer? I found this message:
http://www.xslt.com/html/xsl-list/2004-10/msg00364.html where it appears to
say you can use a statement like this:

<xsl:if test="data($a) instance of xs:integer">

But this looks kind of strange, and maybe it is pseudo-code because it
breaks my transform. 
					<xsl:if
test="./Locations/Location/Address/cbc:Room instance of xs:integer">Room is
an integer</xsl:if>

I want to be able to tell if the cbc:Room node here is an integer:

        <Address>
          <cbc:Postbox languageID="en-us"
languageLocaleID="normalizedString">2105</cbc:Postbox>
          <cbc:Room languageID="en-us"
languageLocaleID="normalizedString">2nd floor</cbc:Room>

          <cbc:StreetName languageID="en-us"
languageLocaleID="normalizedString">Bancroft Way</cbc:StreetName>
          <cbc:CityName languageID="en-us"
languageLocaleID="normalizedString">Berkeley</cbc:CityName>
          <cbc:PostalZone languageID="en-us"
languageLocaleID="normalizedString">94710</cbc:PostalZone>
          <cbc:CountrySubentity languageID="en-us"
languageLocaleID="normalizedString">California</cbc:CountrySubentity>
          <cac:Country>
            <cac:IdentificationCode languageID="en" codeListID="ISO3166-1"
codeListVersionID="0.3"
codeListSchemeURI="urn:oasis:names:specification:ubl:schema:xsd:CountryIdent
ificationCode-1.0" codeListAgencyName="United Nations Economic Commission
for Europe" codeListName="Country"
codeListAgencyID="6">US</cac:IdentificationCode>

          </cac:Country>
        </Address>

Thanks for any help you can give me!
