Re: [xsl] attribute vs { }

["Joerg Heinicke" <joerg.heinicke@xxxxxx>]

Hello Jian,

both versions are correct, the second (so called "attribute value template")
is obviously shorter and mostly more readable. In some situations you need
the longer version.

Example 1: attribute only when condition is true

<test>
    <xsl:if test="$color != 'black'">
        <xsl:attribute name="color"><xsl:value-of
select="$color"/></xsl:attribute>
    </xsl:if>
</test>

Example 2: attribute value comes from another template

<xsl:template match="/"
    <test>
        <xsl:attribute name="color">
            <xsl:apply-templates select="color"/>
        </xsl:attribute>
    </test>
</xsl:template>

<xsl:template match="color">
    <xsl:value-of select="."/>
</xsl:template>

This is a trivial example, but the second template could be much more
complex or even a recursive template.

So, in the most cases I would use the shorter AVT. Sometimes, if it
necessary, I have to use <xsl:attribute/>.

Joerg
