I have a code like this <xsl:stylesheet> <xsl:template name="NameOfTemplate"> <xsl:for-each select="NODE"> <xsl:variable name="id"><xsl:value-of select="@id"/></xsl:variable> <xsl:element name="NEWELEMENT" use-attribute-sets="ELEMENT ATTRIBUTES"/> </xsl:for-each> </xsl:template> <xsl:attribute-set name="ELEMENT ATTRIBUTES"> <xsl:attribute name="NAME"><xsl:value-of select="concat('xxx',$id)"/></xsl:attribute> </xsl:attribute-set> </xsl:stylesheet> In the attribute-set ELEMENT ATTRIBUTES I use the value of the variable and with the built-in processor it work good but with Xalan it can find the name of the variable ( I think is out of scope). How I can do ???

Ciao Giuseppe

There are two problems with your code: the attribute-set name is not valid name because contains spaces, the attribute-set uses a variable that is out of scope.

You can easily replace the following code

<xsl:element name="NEWELEMENT" use-attribute-sets="ELEMENT ATTRIBUTES"/>

with this and get rid of the xsl:attribute-set
<element NAME="{@id}"/>

Hope this helps

In the example I haven't used the same name of the variable and element of my real code. In the real code I not have spaces. I can't use the method u said because I don't have to use the variable only in the name of the element but in many attributes of it. For example:

<xsl:template name="NameOfTemplate">
<xsl:for-each select="NODE">
<xsl:variable name="VALUE"><xsl:value-of select="@id"/></xsl:variable>

<xsl:element name="NEWELEMENT" use-attribute-sets="ELEMENTATTR"/>
</xsl:for-each>
</xsl:template>

<xsl:attribute-set name="ELEMENT ATTRIBUTES">
<xsl:attribute name="ATTR1"><xsl:value-of select="concat('xxx1',$VALUE)"/></xsl:attribute>
<xsl:attribute name="ATTR2"><xsl:value-of select="concat('xxx2',$VALUE)"/></xsl:attribute>
<xsl:attribute name="ATTR3"><xsl:value-of select="concat('xxx3',$VALUE)"/></xsl:attribute>
</xsl:attribute-set>

In the built-in processor it works. Thanks for your help

As explained in the specs only global variables or parameters are visible to attributes-set
http://www.w3.org/TR/xslt#attribute-sets

Chnaged the attribute-se into a named template

<xsl:template name="ELEMENT-ATTRIBUTES">
<xsl:param name="VALUE"/>
<xsl:attribute name="ATTR1"><xsl:value-of select="concat('xxx1',$VALUE)"/></xsl:attribute>
<xsl:attribute name="ATTR2"><xsl:value-of select="concat('xxx2',$VALUE)"/></xsl:attribute>
<xsl:attribute name="ATTR3"><xsl:value-of select="concat('xxx3',$VALUE)"/></xsl:attribute>
</xsl:template>

then you can call the template passing your variable

<xsl:element name="NEWELEMENT" use-attribute-sets="ELEMENTATTR">
<xsl:call-template name="ELEMENT-ATTRIBUTES">
<xsl:with-param name="VALUE" select="$VALUE"/>
</xsl:call-template>
</xsl:element>
