This is undoubtedly happening because these nodes are being selected by 
default and matched by the built-in templates, so their contents are being 
copied to the result tree and written out.

(The Jeni-code in the post cited did not include any of the templates that 
would handle other structures in a real case; if you leave those out, 
you'll get the default behavior, which is as you describe.)

The solution is either to arrange not to select the nodes you don't want, 
or to assure that when they are selected and matched, nothing gets done 
with them. (The latter is commonly done by matching them with empty templates.)

Terms to research: built-in templates; XSLT processing model; semantics of 
xsl:apply-templates and its select attribute.

Short version: try using a template like this

<xsl:template match="company">
  <xsl:apply-templates select="projects"/>
</xsl:template>

to replace the built-in template, which would look like this:

<xsl:template match="company">
  <xsl:apply-templates select="child::node()"/>
</xsl:template>

Cheers,
Wendell
