Yes, if I understand your question correctly. xsl:apply-templates means
"process these nodes, using the best matching template for each one"... the
built-in template for element nodes just calls <xsl:apply-templates/> which
means to process the children of the element.. the built-in template for text
nodes just does <xsl:copy/> which copies the node. You'll override that
template for text nodes with a template that does <xsl:value-of
select="normalize-space(.)"/>, which creates a new text node with the
normalized string.

If the data is in a text node, then no. You just have to make sure to use
xsl:apply-templates to get to the text nodes instead of using xsl:value-of on
their parent element.

You are not modifying the source tree in XSLT. You are only creating the
result tree from which the output XML is automatically derived after the
stylesheet is processed.

Yes, you can write it as & # 1 0 ;   or   & # x A ;
but without the spaces in between. That's what I wrote in my email.
Despite the fact that my email goes out as text/plain, your email client
apparently thinks it is being smart by interpreting that as markup. Who
knows how much markup you are missing when you read the posts on this list!
Use some other client :)
