Section[1] only in toc

I have an abnormalÂuse case.

The source file is a book with many articles, however the TOC is to be first level sections of each article and not the article title itself.

Example:

<article>

<info><title></info>Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â-- not included

<section><info><title></info></section>Â Â Â-- included

<section><info><title></info></section>Â Â Â-- included

...

</article>

<article>

<info><title></info>Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â-- not included

<section><info><title></info></section>Â Â Â-- included

<section><info><title></info></section>Â Â Â-- included

...

</article>

Any pointers would be appreciated.

Thanks,

Peter
