I'm new to Perl.

OBJECTIVE

I want to automate editing of textual parts of HTML files.

APPROACH

At the abstract level, an HTML document is a tree of nodes. I want to traverse the tree and edit its text nodes.

PROBLEM

Unfortunately, I can't give a simple demonstration because this website translates HTML tags and special characters in posts. I have to verbalize an example.

Suppose in an HTML file to be edited I have

(a) “ampersand” + “lt;” string to represent a left angle bracket “<”, and

(b) “--” string.

Problem 1

After I've built the tree using HTML::TreeBuilder, the “ampersand” + “lt;” string is printed as an ordinary “<” sign.

This is not acceptable.

Problem 2

After I've built the tree using HTML::TreeBuilder, I edit “--” to “M dash”, i.e., “ampersand” + “mdash;”. Printed output is “ampersand” + “amp;” + “mdash;”

This is not acceptable either.

QUESTION

Could you, pray, help me get correct output.

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;
