I suggest HTML::Parser and a state machine.

You want three states:

Start in idle state and transition to "find telephone number item" when you get a start event for a P tag with class="title", then transition from that to "extract telephone number" when you get a text event containing "Telephone", otherwise return to idle state at the next text event. In "extract telephone number" state, store away the phone number at the first text event matching m/[[:digit:]]/ and return to idle state. If you only have one telephone number per page, you can also abort the parse at that point.

See the documentation for HTML::Parser for more details about that module and any good computer science text for more details about using finite state machines as parsers.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
