Re: [xsl] NullPointerException

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

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).

Regards,
Wendell
