Re: add an attribute to an element, then use it in an

the xml an xsl stuff i wrote here are not real things. just examples
(apparently not very good ones ;-) )
what i'm really working on are templates that create php code, defining
classes, populating objects, setting their properties, etc, etc... i can't
put any of that here, too many lawyers around on this side of the
screen... besides, i think it wouldn't make things clearer

the trouble was not processing the attributes and their values. it was
trying to add new ones. thanks to the people on this list, that's in the
past....

xml:

<music>
    <project name="Winterkalte">
        <release name="Structures of Destruction" year="1997"/>
        <release name="Drum 'n' noise" year="1999"/>
    </project>
</music>


xsl:

<xsl:template match="music">

    <xsl:variable name="some_name" select="string('genre')"/>
    <xsl:variable name="some_value" select="string('noise')"/>

    <!-- here, with the as="element()" thing, the magic happens -->
    <xsl:variable name="another_stuff" as="element()*">
        <xsl:element name="project">
            <xsl:attribute name="{$some_name}">
                <xsl:value-of select="$some_value"/>
            </xsl:attribute>
        </xsl:element>
    </xsl:variable>

    <xsl:call-template name="attr">
        <xsl:with-param name="stuff" select="project|$another_stuff"/>
    </xsl:call-template>

</xsl:template>

<xsl:template name="attr">
    <xsl:param name="stuff"/>
        <xsl:for-each select="$stuff/@*">
           <xsl:text>attrName: </xsl:text>
           <xsl:value-of select="name()"/>
           <xsl:text>&#10;attrValue: </xsl:text>
           <xsl:value-of select="."/>
           <xsl:text>&#10;&#10;</xsl:text>
        </xsl:for-each>
</xsl:template>

output:

attrName: name
attrValue: Winterkalte

attrName: genre
attrValue: noise
