The standard design pattern is to define a template rule for each
element, and in each such template rule, call apply-templates to process
the children. That way you do a depth-first traversal of the entire
tree, processing each element as it is encountered. If the source format
is similar to the result format, you define an identity template rule as
the default rule, so things just get copied across.
For example
<xsl:template match="bold">
<b><xsl:apply-templates/></b>
</xsl:template>
processes the <bold> element, replacing it with a <b> element, and
calling apply-templates to process all its children (text nodes and
element nodes) with their appropriate rules.
You don't ever need to use xsl:value-of, and normally you shouldn't use
it except when processing a node that you know has no children.

Subject: [xsl] apply-templates and XHTML's <p> tag
This would be none too hard in Perl. But I am stumped
for it in XSLT. When one does...
<xsl:apply-templates select="foo"/>
...XSLT seeks out and does all the <foo> tags
and inflicts the foo template to them. I get that.
But when parsing an XHTML <p> tag, it may
have text mish-mashed in and between <b> and <i>
and <span> tags...in no fixed order.
I will lose all the style stuff if I just do...
<xsl:template match="p">
<xsl:value-of select="."/>
</xsl:template>
...as the <b>, <i> and <span> will go bye-bye with
all their text siphoned out from them, yes? I don't
want that, obviously.
Cool would be to split <p> into a sequence of <foo>
tags with the <b> and <i> as attributes for some,
not on others.
Can someone point me at a tutorial or how-to which
illustrates an XSLT-ish method for dealing sequentially
with a mixed bunch of text and tags?
Thanks,
Gan
