Apply multiple xsl match template on a xml

Hi friends, I'm new to XML/XSLT...can you help as usual please

Scenario is, I have several xml files where I need to remove certain sections based on the value I specify. Basically to appply multiple xslt templates on a XML document.

please check the attached sample xml and below xslt document (I couldnt attach it)
sample.xml: contains 4 sections.
testone.xslt: Has got one template to remove "First" section. this works fine.
testtwo.xslt: Has got two templates to remove "First" and "Third" section. this isnt working as expected.

I was trying to apply multiple templates on a single document in one go.

thanks in advance.
