echopoint.ui.template.taghandlers
Class HtmlBodyCssStripper

java.lang.Object
  echopoint.ui.template.taghandlers.HtmlBodyCssStripper

All Implemented Interfaces:

java.io.Serializable, TagHandler

public class HtmlBodyCssStripper

extends java.lang.Object

implements TagHandler, java.io.Serializable

The HtmlBodyCssStripper tag handler removes all traces of the HTML and BODY tags during parsing. This allows full HTML files to be included as fragments into further enclosing HTML. This handler will extract CSS links (via LINK tags), META tags and also STYLE tags and place them into the TemplateParseContext. This fix up allows for CSS support that were otherwise wihtin the HTML section.

Method Summary

void	executeTag(ParseContext context, PositionReader input, boolean parseTime) Does not execution and hence no content is placed in these positions
long	getLineNumber() Returns the line number at which this tag handler was invoked.
java.lang.String	getNameProperty() Called to get the identification tag attribute property called "name".
java.util.Map	getProperties() Called to get a Map of tag attribute properties and their values.
long	getTagLength() Get the length of the area in the sourcefile.
long	getTagStart() Get start position of the area in the sourcefile this handler processes.
SGMLTag	parseTag(CompilationContext context, PositionReader input, long startPosition, SGMLTag startTag) Parse the HTML, BODY tag or both.
void	postParsePostProperties(CompilationContext context) This method is called after the tag has been compiled and AFTER any tag properties have been processed.
void	postParsePreProperties(CompilationContext context) This method is called after the tag has been compiled but BEFORE any tag properties have been processed.

Method Detail

executeTag

public void executeTag(ParseContext context,
                       PositionReader input,
                       boolean parseTime)
                throws java.lang.Exception

Does not execution and hence no content is placed in these positions

Specified by:

executeTag in interface TagHandler

Throws:

java.lang.Exception - anything can happen .. and throw an Exception which is caught in PageParser

getTagLength

public long getTagLength()

Get the length of the area in the sourcefile. The area this handler processes is skipped in the inputfile.

Specified by:

getTagLength in interface TagHandler

getTagStart

public long getTagStart()

Get start position of the area in the sourcefile this handler processes.

Specified by:

getTagStart in interface TagHandler

parseTag

public SGMLTag parseTag(CompilationContext context,
                        PositionReader input,
                        long startPosition,
                        SGMLTag startTag)
                 throws java.io.IOException

Parse the HTML, BODY tag or both.

Specified by:

parseTag in interface TagHandler

Parameters:

context - The CompilationContext involved

input - The PositionReader, located after the Name token of the Tag

startPosition - The Position parsing of this token began

startTag - the SGMLTag found in the file.

Throws:

java.io.IOException

getProperties

public java.util.Map getProperties()

Description copied from interface: TagHandler

Called to get a Map of tag attribute properties and their values. The keys of the of the map are expected to be the tag attribute property names and the values are expected top be the tag attribute property values.

Specified by:

getProperties in interface TagHandler

See Also:

TagHandler.getProperties()

getNameProperty

public java.lang.String getNameProperty()

Description copied from interface: TagHandler

Called to get the identification tag attribute property called "name". This may not be present and hence this method could return null.

Specified by:

getNameProperty in interface TagHandler

See Also:

TagHandler.getNameProperty()

getLineNumber

public long getLineNumber()

Description copied from interface: TagHandler

Returns the line number at which this tag handler was invoked. This can be obtained from the PositionReader at parse time.

Specified by:

getLineNumber in interface TagHandler

Returns:

the line number at which this tag handler was invoked

See Also:

TagHandler.getLineNumber()

postParsePreProperties

public void postParsePreProperties(CompilationContext context)

Description copied from interface: TagHandler

This method is called after the tag has been compiled but BEFORE any tag properties have been processed. This allows the tag handler to do some things before actual (and potentially repeated) execution.

Specified by:

postParsePreProperties in interface TagHandler

Parameters:

context - The CompilationContext involved

See Also:

TagHandler.postParsePreProperties(CompilationContext)

postParsePostProperties

public void postParsePostProperties(CompilationContext context)

Description copied from interface: TagHandler

This method is called after the tag has been compiled and AFTER any tag properties have been processed. This allows the tag handler to do some things before actual (and potentially repeated) execution.

Specified by:

postParsePostProperties in interface TagHandler

Parameters:

context - The CompilationContext involved

See Also:

TagHandler.postParsePostProperties(echopoint.template.CompilationContext)
