Re: func:function and func:result

Hello,

you just need two changes:
- enclose the generated output by <func:result>...</func:result> (that is
what func:result is intended for)
- use xsl:copy-of to retrieve the result.

That's is (find it at bottom), just works under xalan 2.7.1 and DataPower
compiler.:

[stammw@br8ggx73 xalan-j_2_7_1]$ java -jar xalan.jar -IN some.xml -XSL
genexslt.xsl ; echo
<?xml version="1.0" encoding="UTF-8"?><INVOIC_TYPE><xsl:if
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" test="string-length
($invoic_type)&gt;0"><xsl:value-of select="$invoic_type_final"/>
</xsl:if></INVOIC_TYPE>
[stammw@br8ggx73 xalan-j_2_7_1]$

Saxon has a problem with it:
C:\saxon>java -jar saxon9.jar a.xml genexslt.xsl

Hallo,

i am using Xalan 2.7.1 and exslt.
I habe Problems with func:result.

I want to have as result a part of xslt code.

My Example:

Function:
    <func:function name="my:getElement">
        <xsl:param name="variableName"/>
        <xsl:param name="variableName_final"/>
        <xsl:param name="elementName"/>
        <xsl:element name="{$elementName}">
            <xsl:element name="xsl:if">
                <xsl:attribute
name="test"><xsl:text>string-length($</xsl:text><xsl:value-of
select="$variableName"/><xsl:text>)>0</xsl:text></xsl:attribute>
                <xsl:element name="xsl:value-of">
                    <xsl:attribute
name="select"><xsl:text>$</xsl:text><xsl:value-of
select="$variableName_final"/></xsl:attribute>
                </xsl:element>
            </xsl:element>
        </xsl:element>
        <func:result/>
    </func:function>

Call of the Function:
<xsl:value-of
select="my:getElement('invoic_type','invoic_type_final','INVOIC_TYPE')"/>

I get the failure:
misplaced literal result in a func:function container.

But it works for me.

This doesnt work:

    <func:function name="my:getElement">
        <xsl:param name="variableName"/>
        <xsl:param name="variableName_final"/>
        <xsl:param name="elementName"/>
        <func:result>
        <xsl:element name="{$elementName}">
            <xsl:element name="xsl:if">
                <xsl:attribute
name="test"><xsl:text>string-length($</xsl:text><xsl:value-of
select="$variableName"/><xsl:text>)>0</xsl:text></xsl:attribute>
                <xsl:element name="xsl:value-of">
                    <xsl:attribute
name="select"><xsl:text>$</xsl:text><xsl:value-of
select="$variableName_final"/></xsl:attribute>
                </xsl:element>
            </xsl:element>
        </xsl:element>
        </func:result>
    </func:function>

Do somebody know, what i can do to fix the problem? Maybe older version
helps?
Thx,
Tamer
