Parse & Download HTML pages

I want to write a Perl script that does two things:

1. Parse a set of HTML pages in different directories recursively and extract all <A HREF=.....> </A> tags into separate text files while maintaining the directory structure. The text files have to reside in the same directories as the html pages. (Note that tags/links are to html pages).

2. Use the extracted tags from text files and download the html pages and save them to the respective directories.

I have managed to extract the tags but into a single file. The directory structure needs to be maintained. I would enter the home directory and the script should do the extraction and download recursively.

Appreciate your help.

this may be off topic, but have you tried using the tool wget?

I dont think wget can work recursively through a directory structure, downloading html pages against links in the text files. If it can please let me know how.

Remember I need to fire this off from a home directory, all downloaded html pages will be placed in the same folder as the text file containing the links.

wget -r http://www.yahoo.com

does a recursive, as defined by the -r, get of the entire website and preserves the directory structures completely.

I have managed to extract the links. Can someone tell me how to extract the actual links (portion between quotes) in the following examples :

<A HREF="htmlsrpl.html#bascomlopt">Basic command-line options:</A>
<A HREF="htmlsrpl.html#old">old="..."</A>
<A HREF="htmlsrpl.html#upcase">upcase=1</A>
<A HREF="htmlsrpl.html#new">new="..."</A>
<A HREF="htmlsrpl.html#old">old="..."</A>
<A HREF="htmlsrpl.html#intags">intags=1</A>
<A HREF="htmlqref.html#syntax">tags</A>
<A HREF="htmlsrpl.html#inclexcl">Element inclusion/exclusion command-line options:</A>
<A HREF="htmlsrpl.html#inside">inside=...</A>
<A HREF="htmlqref.html#syntax">elements</A>
<A HREF="htmlsrpl.html#outside">outside=...</A>
<A HREF="htmlsrpl.html#inmost">inmost=...</A>
<A HREF="htmlsrpl.html#inside">inside=</A>
<A HREF="htmlqref.html#inline">&lt;IMG&gt;</A>
<A HREF="htmlqref.html#br">&lt;BR&gt;</A>
<A HREF="htmlchek.html">htmlchek</A>

I need to pass these as a variable.

Thanks for the responses.
