Subject: Re: [xsl] Nodeset problem From: "Jesper Tverskov" <jesper@xxxxxxxxxxx> Date: Sat, 21 Jul 2007 22:14:22 +0200 |
Hi All,
Being new to xsl, this has me completly befuzzled - either that or my brain gave up and went on holiday! - so any help would be greatly appreciated.
I have an XML file that I'm parsing that has many entries of data. I can happily extract the data but I need to validate certain components of it.
The problem is that what I need to validate against is data contained within another file (containing lookup data if you like):
<Groups> <Company ID='000011'> <Foo ID='01234567'/> <Foo ID='13123123'/> <Foo ID='1232132'/> <Foo ID='55534332'/> </Company> <Company ID='000131'> <Foo ID='23423432'/> <Foo ID='23236543'/> <Foo ID='0043543'/> </Company> </Groups>
So, if I grab the string 0043543 from the original XML I need to compare it with the lookup to see if it exists. If it does then I do nothing, otherwise I record a failure entry. (The check should be against any company - it's simply to see if the string exists <anywhere> in the above file)
The stylesheet I'm calling with the original data is:
<xsl:variable name="lookupfile" select="lookup.xml'"/> <xsl:variable name="foonodes" select="document($lookupfile)"/>
<xsl:key name="list" match="entry" use="Foo_Number"/>
<xsl:template match="/"> <FooValidator>
<xsl:for-each select="/doc/entry[generate-id(.)=generate-id(key('list',Foo_Number))]"> <xsl:variable name="foo" select="Foo_Number"/>
<!-- Call foocomparison to see if "foo" exists in lookup file (nodes) --> <xsl:call-template name="foocomparison"> <xsl:with-param name="foo" select="$foo"/> <xsl:with-param name="foolist" select="$nodes"/> </xsl:call-template> </xsl:for-each>
</FooValidator> </xsl:template>
<xsl:template name="foocomparison"> <xsl:param name="foo" select="normalize-space(.)"/> <xsl:param name="foolist"/>
<xsl:choose>
<!-- <xsl:when test="not(string-length($mid)=0) and $foolist[contains(.,$foo)]"> <xsl:text>Valid FOO</xsl:text> </xsl:when> <xsl:otherwise> <Invalid> <xsl:text>Error: FOO doesn't exist: </xsl:text> <foo><xsl:value-of select="$mid"/></foo> </Invalid> </xsl:otherwise> -->
<xsl:when test="not(string-length($foo)=0) and contains($foolist,$foo)"> <xsl:text>Valid FOO</xsl:text> </xsl:when> <xsl:otherwise> <Invalid> <xsl:text>Error : FOO doesn't exist </xsl:text> <foo><xsl:value-of select="$foo"/></foo> </Invalid> </xsl:otherwise>
</xsl:choose> </xsl:template>
But this just always gives me Error:... even if the value I pass in exists anywhere in the lookup file :(
I'm guessing that the $nodes variable is rubbish and not doing what I think it should?
Is this complete nonsense? Or am I going insane? Laaaa la la de dee di dum - yup :)
Thanks All,
Andy
