RE: template name in attributes

You've got some pretty deep misunderstanding of what goes in the "match"
attribute, because two of us have tried to explain your mistake and somehow
you haven't grasped it.

You might find this little tutorial on patterns helpful:

http://www.saxonica.com/documentation/patterns/intro.html

Note also that xsl:apply-templates does not have a match attribute, it only
has a select attribute.

so if i also have:

<xsl:template match="login">
    ...
</xsl:template>

<xsl:template match="t_news">
    ...
</xsl:template>

<xsl:template match="t_threads">
    ...
</xsl:template>

it has to be changed to:

<xsl:template match="left">
     <xsl:for-each select="box">
         <xsl:apply-templates match="@name"/>
     </xsl:for-each>
</xsl:template>

for it to automatically detect from the attribut value which 
template to 
process?

i have the xml:

<left>
    <box name="login"/>
    <box name="quicksearch"/>
    <box name="t_news"/>
    <box name="t_threads"/>
</left>

and the xsl:

<xsl:template match="left">
    <xsl:for-each select="box">
        <xsl:apply-templates select="@name"/>
    </xsl:for-each>
</xsl:template>

This much is kosher.

<xsl:template match="quicksearch">
   ...
</xsl:template>

This, however, doesn't work as expected because the value of 
the match 
attribute should [usually] be the name of the matched 
element or attribute, 
not their values.  Thus, it would something like:

match="@name"

or

match="@name[. = 'quicksearch']"

The "usually" above is because it's possible to match using non 
name-specific expressions: node() to match any node, text() 
for text nodes, 
@* for attributes, etc.


why is the output only the value of the attribute not the 
template that
matches the value of the attribute?

So now we know why the template doesn't fire.  The "value of 
the attribute" 
is being output because XSLT has default, behind-the-scenes 
templates that 
automatically output certain nodes, if not overridden.  
Thus, if you left 
things as they were, then add the following template, you 
wouldn't get even 
the attribute value output:

<xsl:template match="@*"/>
