Url parsing

Clean link from trackers, sanitize

UrlLocation.get_cleaned_link()

To obtain domain

UrlLocation(link).get_domain()

HTTP processing

Identification of valid codes

PageResponseObject().is_valid()

Identification of invalid codes

PageResponseObject().is_invalid()

Some codes might not indicate that this page is valid, and is not invalid. For example if our crawler is throttled because of too many requests we do not know yet if the page is valid, or not.

Page definitions

Easy access to HTML properties

page = HtmlPage(url, contents)
page.get_title()
page.get_description()

Easy access to RSS properties

page = RssPage(url, contents)
page.get_title()
page.get_description()
page.get_entries()

Easy access to Opml properties

page = OpmlPage(url, contents)
page.get_entries()
