Dear monks,
I've just worked out a solution for a specific problem I had to solve, and I'd like to share the results.
However, I'm unsure about two things:
- if that would actually be of help for anyone
- suppose that it would, where and how to submit/place it so that it would be available for those that might need/like it, without being in the way for all the others that might found their way to the monastery
My questions:
- Should I post/submit this code somewhere ?
- If yes: what would be the recommended way to proceed ?
Specifically, I wanted to be able to extract links _and_ the "associated text" - even if that is a fairly vague notion.
So I decided to write the code that, given the following HTML (note the intentionally nested links and somewhat sloppy HTML):
<garbage>
<a href="URL1"> text1.0 <img src="SRC1"> text1.1 <br>
<garbage2> text1.2
<a href="URL2"> text2.0 <img src="SRC2"> text2.1 <br> <garbage2>
<garbage3> text2.2
<a href="URL3"> text3.0 <img src="SRC3"> text3.1 <br> <garbage3>
text3.2 <x1 a="a" b="b"> text3.3
</a>
text2.3 <haha>
</a>
text1.3 <oho>
<a href="URL4"> text4.0 <img src="SRC4"> text4.1 <br> <garbage4>
text4.2 <x1 a="a" b="b"> text4.3
</a>
text1.4
</a>
would produce the following (or similar) output:
A URL3
TEXT: ' text3.0 text3.1
text3.2 text3.3
'
A URL2
TEXT: ' text2.0 text2.1
text2.2
text2.3
'
A URL4
TEXT: ' text4.0 text4.1
text4.2 text4.3
'
A URL1
TEXT: ' text1.0 text1.1
text1.2
text1.3
text1.4
'
I did my
search homeworks and found a series of good nodes; among them,
Extracting full links from HTML,
Process a HTML file to get information from it.,
Getting to grips with HTML::Parser.
I decided to go for a first attempt with
HTML::Parser; I probably will continue and add at least a few of other code variants, as I'm curious to get my own hands-on knowledge about
HTML::LinkExtractor and
HTML::TokeParser.
The code I've came up so far is on my
Scratchpad.
Thank you for any help/suggestions/opinions.
