So, given a set of simple html pages with references in the format
<i>Reference Title</i> (Author, year)
Or sometimes (Author, year, additional information)
embedded in definitions of the format

<p>
<b>Article title<b>

<p>
Article text including <i>Reference Title</i> (Author, year) and other text, including perhaps <i>Reference Title 2</i> (Author, year)

Is there a tool to build an index page, where the index entry links to the <b>Article title<b> ?

Better, is there a tool that'll also modify the 1st page to make the A#namedlink references that the index points to, too?
