HTML Parsing with jsoup
Details
To check HTML we parse it into an internal (DOM-like) representation. For this task we use jsoup HTML parser, an open-source parser without external dependencies.
To quote from the jsoup website:
jsoup is a Java library for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jquery-like methods.
Find details on how HtmlSC
implements HTML parsing in the HTML encapsulation concept.Relevance
Check HTML programatically by using an existing API that provides access and finder methods to the DOM-tree of the file(s) to be checked.Requirements
- few dependencies, so the HtmlSC binary stays as small as possible.
- accessor and finder methods to find images, links and link-targets within the DOM tree.
Alternatives
- HTTPUnit: a testing framework for web applications and -sites. Its main focus is web testing and it suffers from a large number of dependencies.
- jsoup: a plain HTML parser without any dependencies (!) and a rich api to access all HTML elements in DOM-like syntax.
Checking of external links postponed
Details
In the current {revision} we won’t check external links. These checks have been postponed to later versions.String Similarity Checking with Jaro-Winkler-Distance
Details
The small java-string-similarity library (by Ralph Allen Rice) contains implementations of several similarity-calculation algorithms. As it is not available as public binary, we use the sources instead, primarily:
