Class Clean
public class Clean
extends java.lang.Object
Clean up misuse of presentation markup. Filters from other formats such as Microsoft Word often make excessive use of
presentation markup such as font tags, B, I, and the align attribute. By applying a set of production rules, it is
straight forward to transform this to use CSS. Some rules replace some of the children of an element by style
properties on the element, e.g.
...
.
...
Such rules are applied to the element's content and then to the element itself until none of the rules more apply.
Having applied all the rules to an element, it will have a style attribute with one or more properties. Other rules
strip the element they apply to, replacing it by style properties on the contents, e.g.
...
.
... These rules are applied to an element before processing its content and replace the current element by the first
element in the exposed content. After applying both sets of rules, you can replace the style attribute by a class
value and style rule in the document head. To support this, an association of styles and class names is built. A
naive approach is to rely on string matching to test when two property lists are the same. A better approach would be
to first sort the properties before matching.

bQ2Div
public void bQ2Div(Node node)
Replace implicit blockquote by div with an indent taking care to reduce nested blockquotes to a single div with
the indent set to match the nesting depth.
cleanTree
public void cleanTree(Lexer lexer,
Node doc)
Clean an html tree.

cleanWord2000
public void cleanWord2000(Lexer lexer,
Node node)
This is a major clean up to strip out all the extra stuff you get when you save as web page from Word 2000. It
doesn't yet know what to do with VML tags, but these will appear as errors unless you declare them as new tags,
such as o:p which needs to be declared as inline.

dropSections
public void dropSections(Lexer lexer,
Node node)
Drop if/endif sections inserted by word2000.

emFromI
public void emFromI(Node node)
Replace i by em and b by strong.
isWord2000
public boolean isWord2000(Node root)
Check if the current document is a converted Word document.
true
if the document has been geenrated by Microsoft Word.
list2BQ
public void list2BQ(Node node)
Some people use dir or ul without an li to indent the content. The pattern to look for is a list with a single
implicit li. This is recursively replaced by an implicit blockquote.
nestedEmphasis
public void nestedEmphasis(Node node)

pruneSection
public Node pruneSection(Lexer lexer,

purgeWord2000Attributes
public void purgeWord2000Attributes(Node node)
Remove word2000 attributes from node.
stripSpan
public Node stripSpan(Lexer lexer,
