Filtering Result with dynamic value?

[FhHouse]

I have a list full of items, each item has a categoryid,
i want to filter the list of items by the categoryid in my xsl code, I can do this if i specify what my category id is, but i wanted to try and make it generic, don't know if that makes sense, but please look at the code below.
I am generating my xml using asp and the FilterValue & FilterLabel nodes will vary depending on different params sent to the asp.

# XML
<Root>
<FilterValue>2</FilterValue>
<FilterLabel>CategoryID</FilterLabel>
<List>
<Item>
<Title>Title 1</Title>
<Value>Value 1</Value>
<CategoryID>2</CategoryID>
</Item>
<Item>
<Title>Title 2</Title>
<Value>Value 2</Value>
<CategoryID>2</CategoryID>
</Item>
<Item>
<Title>Title 3</Title>
<Value>Value 3</Value>
<CategoryID>4</CategoryID>
</Item>
</List>
</Root>

# XSL
<xslaram name=&quot;FilterLabel&quot;><xsl:value-of select=&quot;/Root/FilterLabel&quot;></xslaram>

<xsl:for-each select=&quot;Root/List/Item&quot;>
<br></br>

<!-- this works call the node by name 'CategoryID' -->
<xsl:if test=&quot;CategoryID = /Root/FilterValue&quot;>
Title: <xsl:value-of select=&quot;Title&quot; />, <xsl:value-of select=&quot;CategoryID&quot; />
</xsl:if>

<!-- this does not work call the node by variable value -->
<xsl:if test=&quot;$FilterLabel = /Root/FilterValue&quot;>
Title: <xsl:value-of select=&quot;Title&quot; />, <xsl:value-of select=&quot;CategoryID&quot; />
</xsl:if>

</xsl:for-each>

I have tried different things such as
if test=&quot;node()[$FilterLabel] = /Root/FilterValue&quot;

even calling the template with the filter built in
<xsl:template match=&quot;Root/List/Item[CategoryID = /Root/FilterValue]&quot;>

once again the above works, but these don't
this throws error
<xsl:template match=&quot;Root/List/Item[$FilterLabel = /Root/FilterValue]&quot;>

this has strange results
<xsl:template match=&quot;Root/List/Item[node()[/Root/FilterLabel = /Root/FilterValue]&quot;>

any ideas?

I was able to get it by putting the CategoryID into an attribute of the Item <Item CategoryID=&quot;2&quot;>, since it is the only attribute I can access it without knowing what it is, so this works unless I need to have more than this 1 attribute.

<xsl:template match=&quot;Root/List/Item[@node() = /Root/FilterValue]&quot;>
