I think my problem is very simple but I am having trouble making it to
work.
The xsl code should go through the document and find all the <super>
tags. Instead I get this:

[ERROR]: The markup in the document preceding the root element must be
well-formed.
(The xml file is well-formed but not the .fo file.  )

<xsl:template match="node()">
<xsl:copy>
<xsl:copy-of select="@*"/>
    <xsl:if test="contains(. ,'<sub>')">
       <fo:inline baseline-shift="super" font-size=".75em">
         <xsl:text>FOUND SUPER </xsl:text>
      </fo:inline>
  </xsl:if>
</xsl:copy>
</xsl:template>

As Stuart pointed out, your document isn't well-formed, which is why you are getting this error.

Yet even when you fix this, your technique won't work. This is due to a fundamental misconception you are laboring under with respect to the way XSLT handles a document.

By definition, the XSLT code *cannot* "go through the document and find all the <super> tags". This is because it does not see tags at all. A tag in an XML document is merely, in an XSL system, a notation that indicates the beginning of an element. By the time an XSLT processor sees it, the existence of this element has been noted (that's the job of the parser) and the tag is no more. It's the *element* that you match on or "find". You can't find its beginning apart from finding the whole thing -- and when you do, there won't be any tag there. (It'll have a type name, 'super', but no "tag".)

You are thinking of XSLT as a string-processing routine. It's not. Spend a few minutes on an introductory XSL tutorial and see if it helps illuminate things. Concentrate your attention on the XPath (XSLT) data and processing models.

Once you get the hang of it you'll find it's a very powerful way of working, and fun too.

Enjoy!
Wendell
