Different way for XSLT to loop through Nodes
Question
I've recently come upon a little smal challenge, while I do believe that a lot of people just stick with the -ForEach- loop as we usually do, I'm trying to think outside and see what alternative ways we have to actually to the same thing but in a different way.
There is another way to actually loop through the child nodes in this XSLT but I'm having a little hard time to actually figure it out. I've been searching through the forum without an answer but perhaps someone can point me in the correct direction.
My codes looks like this atm:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>Cars</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
<xsl:for-each select="autoads/ad">
<xsl:if test="type = 2">
<tr>
<td><xsl:value-of select="name"/></td>
<td><xsl:value-of select="model"/></td>
<td><xsl:value-of select="regyear"/></td>
<td><xsl:value-of select="price"/></td>
<td><xsl:value-of select="adtext"/></td>
</tr>
</xsl:if>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
and the XML looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="uppgift1.xsl"?>

What I'm trying to do is actually do the same thing as I do with <xsl:for-each select="autoads/ad">
Just not using the actually For-Each.
I've been trying to use the "match" function and template and then using "apply-templates" but I cant get it too work so that the values actually end up in boxes as the first example:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>Cars</h2>
<xsl:apply-templates select="//ad" />
<table border="1">
<tr bgcolor="#9acd32">
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="ad">
<td><xsl:value-of select="name" /></td>
<!-- <td><xsl:apply-templates select="autoads/ad/model"/></td> -->
<!-- <td><xsl:apply-templates select="autoads/ad/regyear"/></td> -->
<!-- <td><xsl:apply-templates select="autoads/ad/price"/></td> -->
<!-- <td><xsl:apply-templates select="autoads/ad/adtext"/></td> -->
</xsl:template>
<!-- </table> -->
</xsl:stylesheet>
Anyone have any good tips on how to think?

a couple of tips :
-first, it is adviced to use xsl version 2 (released in 2007 :P )
-second, apply-template is more efficient than for-each and it is designed specially for the thing you want to achieve. So here is how i would use apply-template in your code :
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:template match="/">
<html>
<body>
<h2>Cars</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
<xsl:apply-templates select="/autoads/ad"/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="/autoads/ad">
<xsl:if test="type = 2">
<tr>
<td><xsl:value-of select="name"/></td>
<td><xsl:value-of select="model"/></td>
<td><xsl:value-of select="regyear"/></td>
<td><xsl:value-of select="price"/></td>
<td><xsl:value-of select="adtext"/></td>
</tr>
</xsl:if>
</xsl:template>

There is nothing wrong with using xsl:for-each - but if you prefer using xsl:apply-templates , you can do:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/autoads">
<html>
<body>
<h2>Cars</h2>
<table border="1">
<tr>
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
<xsl:apply-templates select="ad[type=2]"/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="ad">
<tr>
<td>
<xsl:value-of select="name"/>
</td>
<td>
<xsl:value-of select="model"/>
</td>
<td>
<xsl:value-of select="regyear"/>
</td>
<td>
<xsl:value-of select="price"/>
</td>
<td>
<xsl:value-of select="adtext"/>
</td>
</tr>
</xsl:template>
</xsl:stylesheet>
