function readHTMLFile​

Parse a HTML file and return an HTMLElement AST.

HTMLElement readHTMLFile(loc file, loc base=file, bool trackOrigins=false, bool includeEndTags=true)

function writeHTMLString​

Pretty-print the HTMLElement AST to a string.

str writeHTMLString(HTMLElement dom, str charset="UTF-8", HTMLEscapeMode escapeMode = baseMode(), bool outline=false, bool prettyPrint=true, int indentAmount=4, int maxPaddingWidth=30, HTMLSyntax \syntax=htmlSyntax(), bool dropOrigins=true)

This function uses JSoup's DOM functionality to yield a syntactically correct (X)HTML string.

function writeHTMLFile​
