Hi,

  well, I looked more deeply at xslt and did this:

source:

<song>
<head>
<title>The winner takes it all</title>
</head>
<body>
<line>
<chord value=" "/>I don't wanna <chord value="Gb7"/>talk
about things we've <chord value="Db/F"/>gone trough, though
it's hurting <chord value="Dbm/Eb"/>me, now it's
histo<chord value="Db"/>ry.
</line>
</body>
</song>

xsl:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";>
 
  <xsl:template match="song">
   <xsl:processing-instruction name="cocoon-format">type="text/html"</xsl:processing-instruction>
   <html>
    <xsl:apply-templates/>
   </html>
  </xsl:template>
 
  <xsl:template match="head">
   <head>
    <title><xsl:value-of select="title"/></title>
   </head>
  </xsl:template>
 
  <xsl:template match="body">
   <body>
    <h1>
     <xsl:value-of select="/song/head/title"/>
    </h1>
    <xsl:apply-templates/>
   </body>
  </xsl:template>

  <xsl:template match="line">
   <table cellpadding="0" cellspacing="0">
    <tr>
     <xsl:apply-templates select="chord"/>
    </tr>
    <tr>
     <xsl:apply-templates mode="lyrics"/>
    </tr>
   </table>
  </xsl:template>
 
  <xsl:template match="chord">
   <td><font size="-1"><b>
    <xsl:value-of select="@value"/>
   </b></font></td>
  </xsl:template>
 
  <xsl:template match="text()" mode="lyrics">
   <td>
    <xsl:value-of select="."/>
   </td>
  </xsl:template>
 
</xsl:stylesheet>

which produces quite reasonable output (read: which produces
the think I wanted :-))) The same think, I'd say, could be
realized with fo's, but I don't know any parser :-(( It's
more straightforward than I thought it would be... I decided
to use cocoon's producer ability to implement the automatic
transposition in Java... I think it's not what XSLT is here
for.

what i'd like to ask, whether somebody has an idea about how
to do such things as: "replace all occurences of 'b' in
string with '<sup>b</sup>'" to automatically render Db into
D<sup>b</sup>... I tried to implement this for more
than two hours but found no way :-( (of course except a giant
<xsl:choose> with all possible chord values enumerated...)
