Hi Jarkko,
the answer was already given by Joerg Pietschmann. In XSLT a
id()-function exists, which Cindy is using (only in a wrong way). When
you want to use id() you have to declare an attribute in the DTD as ID.
You will have fast access to this element, which has the value given as
parameter to id(). It's similar to the key(), but you don't need to
construct a key(), you only need the DTD.
The problem Cindy has with her code is the writing of the expression. A
function must not be written after an XPATH. So she must change the
context before using id() to the other file:
<xsl:for-each select="$docnode">
<xsl:value-of select="id($from)"/>
</xsl:for-each>
Regards,
Joerg

Hi ,
The following code gets me the first div3 element w/in the odes document
(as expected):
<xsl:variable name="from" select="@from"/>
<xsl:variable name="docnode"
select="document('../texts/odes.xml')"/>
<xsl:message>
<xsl:value-of select="$docnode//div3"/>
</xsl:message>
But when I try to find an element whose id attribute is equal to the
value of the 'from' variable, I get an error saying "Unexpected token
[<function>] in path expression."
<xsl:variable name="from" select="@from"/>
<xsl:variable name="docnode"
select="document('../texts/odes.xml')"/>
<xsl:message>
<xsl:value-of select="$docnode//id($from)"/>
</xsl:message>
Sorry, if I dont understand this correctly, but error is that U are
looking /selecting the value of id elements from attribute. Is this
what U really want? It would help to see the xml file (atleast for me).
Jeni, Michael, some other guru could correct me if I´m wrong.
Cheers
Jarkko
