Few DocBook queries and DSSSL

Hi, I'm not sure if these questions are appropriate in this forum. I'm pretty new to DocBook. I understood the concept well. I had a few questions.

I'm trying to make a HTML -> DocBook converter. Basically, it will take an HTML file and try to generate DocBook content. I know it may sounds dumb but thats what I'm trying to make. So how do I bring structure ( DocBook ) to an unstructured document ( HTML )?

While I was learning about the formatting of the DocBook content I came across DSSSL. I got many resources online but all of them have a very steep learning curve. Are there any simple books / online tuts that I may have missed?

One problem that I'm not able to solve is, I'm trying to change the way title of my book is formatted. So I made a .dsl file and put the following content:

( element ( bookinfo title )
        ( make paragraph
                font-family-name: "Times New Roman"
                space-before: 10pt
                space-after: 10pt
                font-size: 36pt
                ( process-children )
        )
)

But it simply doesn't show up. Infact the change reflects in all titles except the cover page. The DocBook code is as follows:

<book id="my-new-book" lang="en">
   <bookinfo>
      <title>This is the title of the book!</title>
      <date>12th August 2007</date>
      <releaseinfo>Released by test!</releaseinfo>
      <authorgroup>
         <author>
            <othername>t</othername>
            <surname>stest</surname>
            <firstname>ftest</firstname>
         </author>
      </authorgroup>
   </bookinfo>
   <chapter id="chapter1">
      <title>This is a title of chapter 1</title>
      <sect1 id="sample-sect-1-1">
          <title>This is some text inside a section</title>
          <para>This is a para inside a section</para>
      </sect1>
   </chapter>
   <chapter id="chapter2">
      <title>This is a title of chapter 2</title>
      <sect1 id="sample-sect-1-2">
         <title>This is some text inside a section</title>
         <para>This is a para inside a section</para>
      </sect1>
    </chapter>
</book>
