Features
Word by word comparison
HTML Compare by default performs word by word comparison providing a granular result rather than large amounts of change when in fact only certain words within the text have been changed.
Character by character comparison
The character by character comparison provides changes to character level rather than at word level to accurately identify changes like spelling or grammatical mistakes.
Special HTML table comparison
HTML Compare has specialised processing for tables which conform to W3C HTML table specification. The main goal of HTML table processing is to keep the tables in the comparison output valid to ensure comparison results can be rendered properly in the appropriate application. The HTML table comparison can handle various table changes such as cell content change, row/column addition/deletion and row/column spanning changes.
Ignoring document structure
This feature allows HTML document comparison by ignoring the structure and alignment based on the content for formatting elements such as b, i etc. This can also be extended to block level elements such as div, span etc.
MathML comparison
This feature allows special processing of embedded MathML to produce a valid, renderable comparison output if embedded MathML is valid and renderable.
Inline SVG Comparison
This feature performs XML based inline SVG comparison to identify the changes between two inline SVG files.
CSS and javascript handling
The conflicting CSS and javascript between to HTML documents is handle by the HTML Compare by selecting CSS and javascript from the second document.
