You can use this component if you need to parse any information from any string value which has some syntax logics.
The easiest way to parse data from string in python.
CustomStringParser, the missing simple string parser for python developers.
Note: for html based parsing you should consider using xpath
Imagine you have this kind of content in your string_data with this content:
<div class="section-item">
<div class="section-title">
title1
</div> <!-- end section-title -->
<div class="section-comments">
15
</div> <!-- end section-comments -->
</div> <!--end section-item-->
<div class="section-item">
<div class="section-title">
title2
</div> <!-- end section-title -->
<div class="section-comments">
16
</div> <!-- end section-comments -->
</div> <!--end section-item-->
<div class="section-item">
<div class="section-title">
title3
</div> <!-- end section-title -->
<div class="section-comments">
17
</div> <!-- end section-comments -->
</div> <!--end section-item-->
We need to parse these items:
- title
- comments count
Code to parse this looks like this:
parser = CustomStringParserCore(string_data)
item_parser = ParsingNode('item', '<div class="section-item">', '</div> <!--end section-item-->')
title_parser = ParsingNode('title', '<div class="section-title">', '</div> <!-- end section title -->')
comments_parser = ParsingNode('comments', '<div class="section-comments">', '</div> <!-- end section-comments -->')
# note: our item result will have title and comments inside of it, so we can do this:
item_parser.add_parser(title_parser)
item_parser.add_parser(comments_parser)
# add main parser to the parsing core
parser.add_parser(item_parser)
# call the parse
parser.parse()
<..>
output (print_results(item_parser.results)):
item:
<div class="section-title">
title1
</div> <!-- end section-title -->
<div class="section-comments">
15
</div> <!-- end section-comments -->
title:
title1
comments:
15
item:
<div class="section-title">
title2
</div> <!-- end section-title -->
<div class="section-comments">
16
</div> <!-- end section-comments -->
title:
title2
comments:
16
item:
<div class="section-title">
title3
</div> <!-- end section-title -->
<div class="section-comments">
17
</div> <!-- end section-comments -->
title:
title3
comments:
17
