I have an XML file which looks like this:

<catalog>
<cd>
<title>Empire Burlesque</title> 
<artist>Bob Dylan</artist> 
<country>USA</country> 
<company>Columbia</company> 
<price>10.90</price> 
<year>1985</year> 
</cd>
<cd>
<title>Hide your heart</title> 
<artist>Bonnie Tyler</artist> 
<country>UK</country> 
<company>CBS Records</company> 
<price>9.90</price> 
<year>1988</year> 
</cd>
.
.
.
</catalog>

My xslt looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<table border="1" cellpadding="0" cellspacing="0" width="50%">
<tr>
<td class="heading" colspan="2">Leila's music box</td> 
</tr><tr bgcolor="#9acd32">
<td class="textSmall">Artist</td>
<td class="textSmall">Title</td>
</tr>
<xsl:for-each select="catalog/cd">
<xsl:sort select="artist"/>
<tr>

<xsl:if test = "catalog/cd[starts-with(artist, 'a')]">
<td bgcolor="#B0F3A1">
<xsl:value-of select="artist"/>
</td>
<td bgcolor="#B0F3A1">
<xsl:value-of select="title"/>
</td>
</xsl:if>

<xsl:if test = "catalog/cd[starts-with(artist, 'b')]">
<td bgcolor="#F3A1A5">
<xsl:value-of select="artist"/>
</td>
<td bgcolor="#F3A1A5">
<xsl:value-of select="title"/>
</td>
</xsl:if>
.
.
.

</tr>
</xsl:for-each>

</table>
</xsl:template>

</xsl:stylesheet>

I am attempting to use the <xsl:if ...> statement to check which
letter the artist name begins with, and depending on that, I change
the background colour of the <td> tag.

But this line <xsl:if test = "catalog/cd[starts-with(artist, 'b')]">
is not working. What am I doing wrong???

Any help would me most appreciated!
