There was a thread going where someone else wanted the entire content of
<p>Some text and <br/> some more <b>text</b>.</p> in their output.

They were using <xsl:value-of select="p"> and wondered why they didn't
see all the lovely nested nodes, also.

Michael suggested copy-of or apply-templates.

I said I sometimes use xsl:sequence (instead of value-of, copy-of,
apply-templates) and wondered if there might be side effects to using
xsl:sequence for this purpose that I may not know about....


Thanks!

your message doesn't say what the approach is (other than using sequence
instead of value-of) the subject line gives some clues, but appears
confused.

"Selecting unparsed text from inside a tag"

XSLT has no access to the tags in a source file, assuming you mean
element here the content is always parsed.

The only way of getting text that hasn't been parsed by an XML parser
into XSLT is with the unparsed-text() function, but that never generates
mixed content, it just returns a string, using xsl:value-of or
xsl:sequence on the result of unparsed-text()  makes no difference in
most contexts. If you use xsl:value-of, it generates a text node
directly, if you use xsl:sequence it generates a string, but if that
string is being copied to the result tree, it is implictly wrapped in a
text node.
