Render XML structure using XSLT

Hi,
I'm trying to render a XML structure to HTML using XSLT.
My XML describe the header of a table with a complex and not linear
structure.
The first row of the header table always contains the ServiceName
(attribute name), under I have to show all the other fields with
correct structure.
Can you help me to write XSLT document?

My XML doc:
************************************************** ****************************
<?xml version="1.0" encoding="UTF-8"?>
<data>
<Service depth="6" name="service1" totalDepth="2">
<Field depth="0" name="1.1"/>
<Field depth="0" name="1.2"/>
<Field depth="0" name="1.3"/>
<Field depth="0" name="1.4"/>
<Field depth="0" name="1.5"/>
<Field depth="0" name="1.6"/>
</Service>
<Service depth="8" name="service2" totalDepth="4">
<Field depth="4" name="2.1">
<Field depth="4" name="2.1.1">
<Field depth="0" name="2.1.1.1"/>
<Field depth="0" name="2.1.1.2"/>
<Field depth="0" name="2.1.1.3"/>
<Field depth="0" name="2.1.1.4"/>
</Field>
<Field depth="4" name="2.1.2">
<Field depth="0" name="2.1.2.1"/>
<Field depth="0" name="2.1.2.2"/>
<Field depth="0" name="2.1.2.3."/>
<Field depth="0" name="2.1.2.4"/>
</Field>
<Field depth="4" name="2.1.3.">
<Field depth="0" name="2.1.3.1"/>
<Field depth="0" name="2.1.3.2"/>
<Field depth="0" name="2.1.3.3"/>
<Field depth="0" name="2.1.2.4"/>
</Field>
<Field depth="4" name="2.1.4">
<Field depth="0" name="2.1.4.1"/>
<Field depth="0" name="2.1.4.2"/>
<Field depth="0" name="2.1.4.3"/>
<Field depth="0" name="2.1.4.4"/>
</Field>
</Field>
<Field depth="4" name="2.2">
<Field depth="0" name="2.2.1"/>
<Field depth="0" name="2.2.2"/>
<Field depth="0" name="2.2.3"/>
<Field depth="0" name="2.2.4"/>
</Field>
</Service>
</data>

This is what I want to obtain:
************************************************** ****************************

<td rowspan="3">1.5</td>

<td colspan="16">2.1</td>
<td colspan="4" rowspan="2">2.2</td>
</tr>
<tr>
<td colspan="4">2.1.1</td>
<td colspan="4">2.1.2</td>
<td colspan="4">2.1.3</td>
<td colspan="4">2.1.4</td>
</tr>
<tr>

<td>2.1.1.2</td>
<td>2.1.1.3</td>

</table>
</body>

The following might be helpful:

<?xml version="1.0" encoding="iso-8859-1" ?>
<xsl:stylesheet version="1.0"

<xsl:output

<body>
<table border="1" cellpadding="0" cellspacing="0">

<xsl:apply-templates select="Service" />
</tr>
<tr>
<xsl:apply-templates select="Service/Field" />
</tr>
<tr>
<xsl:apply-templates select="Service/Field/Field[child::*]" />
</tr>
<tr>
<xsl:apply-templates select="child::Service/Field/Field/Field" />
<xsl:apply-templates select="Service/Field/Field[not(child::*)]" />
</tr>
</table>
</body>
</html>
</xsl:template>

<xsl:template match="Service">
<td colspan="{count(descendant-or-self::Field[@depth='0'])}">
<xsl:value-of select="@name" />
</td>
</xsl:template>

<xsl:template match="Service/Field">

Great, but I have other a problem: if I add this following service, the
xslt doesn't work well
----------------------------------------------------------------------------------------------------------------------
<Service name="service3" depth="2" totalDepth="3">
<Field name="3.1" depth="2">
<Field name="3.1.1" depth="0"/>
<Field name="3.1.2" depth="0"/>
</Field>
<Field name="3.2" depth="2">
<Field name="3.2.1" depth="0"/>
<Field name="3.2.2" depth="0"/>
</Field>
</Service>

My XML document has a dynamic structure with unlimited number of
Service node, Field node and Field subnode.
The xslt document work only on a fix structure with maximum 3 level of
Field node.
XML dcoument has 2 different attribute:
- depth: is the number of child (without subnode) for the selected node
(i.e. "service3" has 2 child: "3.1" and "3.2")
- totalDepth: is the maximum deep of Service node. "service3" as
totalDepth="3": Service node + Field node + Field subnode

I think that these attributes can help you.
