Norm:
Maybe I'm completely confused here but if your source has:
<paragraph>This is some text <sub>including some subscripted text</sub> and
then some more text</paragraph>
what you want is as simple as
<xsl:template match="paragraph">
<fo:block>
<xsl:apply-templates/>
</fo:block>
</xsl:template>
<xsl:template match="sub">
<fo:inline baseline-shift="sub">
<xsl:apply-templates/>
</fo:inline>
</xsl:template>
with adjustments for your target language (e.g. you haven't actually said
you are targetting FO, I just guessed).
Now if your source has something more like
<paragraph>This is some text & l t ; sub & g t ; including some subscripted
text & l t ; /sub & g t ; and then some more text</paragraph>
(Note I've introduced extra spaces to work around broken email clients that
don't tolerate honest code.)
Then things are harder, since what you need is a string-processing
language, and XSLT isn't designed for that. (You'd have to walk on your
hands to do it.)
Which is your case?
Sorry to be a nuisance if I haven't understood (yet).

Wendell

I did go through the xpath tutorial and I understand that well now. but,
that does not help solve my problem. What I am trying to do is to find a
way to do subscript and superscript of some text data. The node search
code I mailed earlier does contain the proper < and > followed by a
semicolon. ( the email system I am using is converting < to < and >
to :( ). I am soooo lost and need your help very badly.
The string "<sub>" is not an attribute. It is a value of an element. OK!
just forget what I have done. Pls tell me a way to do a
subscript/superscript!!!!
THANK YOU
Norm
