problems with apply-templates

Help! The apply-templates function is not currently allowing me to
select a specific template... eventhough I tried putting a select
statement, it does not seem to work??? Can someone help show how I can
select the first template and then have it select others? Below is a
sample of the xml as well as the .xsl file when
I do something like the following in the main section it does not seem
to work, it only works when I remove the select statement, and even
then it seems to only be using the first template... any help is
greatly appreciated...

<xsl:apply-templates select="hashref/item[starts-with(@key,'TEST_')]"
/>

<xsl:template match="hashref/item[starts-with(@key,'TEST_')]">

so here your current node is an item node

<xsl:apply-templates select="item[@key='hypothesis_test_results']"/>

so this selects item children (with that attribute) of teh current item
node, but your sample input didnt have any such children, they seem to
be grandchildren below a hashref so perhaps you meant to do

<xsl:apply-templates select="hashref/item[@key='hypothesis_test_results']"/>

Hi, Thanks for the response I will try that. How about when the first
<xsl:apply-templates\> is called? It seems that I cannot get this to
just apply the following template specifically... any ideas? I tried
the following but maybe something is wrong here?

statement to call template

<xsl:apply-templates select="hashref/item[starts-with(@key,'TEST_')]">\>

template to call

<xsl:template match="hashref/item[starts-with(@key,'TEST_')]">

you used a similar wording in your original message and I didn't
understand what you meant then or now. I suspect that you have the
wrong mental model of how xslt is working.
When you use apply-templates you _never_ specify which templates are to
be applied (and there is no real notion of a "next" template, the order
of templates in the stylesheet is not significant). apply-templates uses
a select expression which selects nodes in the input tree.

If you want to call a block of code explictly then you want to use a
named template not a match template and use xsl:call-template rather
than apply-templates. However that isn't normally what you would want to
do for this kind of transform.
