A forgiving HTML/XML/RSS parser. The parser can handle streams and provides a callback interface.
npm install htmlparser2
A live demo of htmlparser2 is available here.
--> Xyz JS! Hooray! --> var foo = '<<bar>>'; That's it?!
Read more about the parser and its options in the wiki.
Get a DOM
DomHandler (known as
DefaultHandler in the original
htmlparser module) produces a DOM (document object model) that can be manipulated using the
DomHandler, while still bundled with this module, was moved to its own module. Have a look at it for further information.
Parsing RSS/RDF/Atom Feeds
const feed = htmlparser2.parseFeed(content, options);
Note: While the provided feed handler works for most feeds, you might want to use danmactough/node-feedparser, which is much better tested and actively maintained.
After having some artificial benchmarks for some time, @AndreasMadsen published his
htmlparser-benchmark, which benchmarks HTML parses based on real-world websites.
At the time of writing, the latest versions of all supported parsers show the following performance characteristics on Travis CI (please note that Travis doesn’t guarantee equal conditions for all tests):
gumbo-parser : 34.9208 ms/file ± 21.4238 html-parser : 24.8224 ms/file ± 15.8703 html5 : 419.597 ms/file ± 264.265 htmlparser : 60.0722 ms/file ± 384.844 htmlparser2-dom: 12.0749 ms/file ± 6.49474 htmlparser2 : 7.49130 ms/file ± 5.74368 hubbub : 30.4980 ms/file ± 16.4682 libxmljs : 14.1338 ms/file ± 18.6541 parse5 : 22.0439 ms/file ± 15.3743 sax : 49.6513 ms/file ± 26.6032
How does this module differ from node-htmlparser?
This module started as a fork of the
The main difference is that
htmlparser2 is intended to be used only with node (it runs on other platforms using browserify).
htmlparser2 was rewritten multiple times and, while it maintains an API that’s compatible with
htmlparser in most cases, the projects don’t share any code anymore.
DefaultHandler and the
RssHandler were renamed to clarify their purpose (to
FeedHandler). The old names are still available when requiring
htmlparser2, your code should work as expected.
