Class A_CmsConfiguredHtmlParser

java.lang.Object
  org.opencms.jsp.parse.A_CmsConfiguredHtmlParser

public abstract class A_CmsConfiguredHtmlParser
extends java.lang.Object

Base class for all classes that are specified for the <cms:parse parserClass="name" param="config" /> tag in the parserClass Attribute.

Entry point for the tag implementation (CmsJspTagParse). The tag will provide a valid CmsObject and it's configuration parameter String to subclasses of this instances. Implementations just choose the type of I_CmsHtmlNodeVisitor they will use for visiting the content to be parsed.

To implement a custom class that may be used with the <cms:parse parserClass="name" param="config" /> tag the only thing that has to be done is to implement the method createVisitorInstance() and return the desired I_CmsHtmlNodeVisitor implementation.

A_CmsConfiguredHtmlParser

protected A_CmsConfiguredHtmlParser()

Default constructor that initializes the internal visitor by using the abstract template method createVisitorInstance().

Method Detail

createVisitorInstance

protected abstract I_CmsHtmlNodeVisitor createVisitorInstance()
                                                       throws CmsException

Subclasses have to create their desired instance for parsing the html here.

You have access to getCmsObject() and getParam() already here and may pass those to the visitor to return.

Returns:

the instance to be used for parsing the html

Throws:

CmsException - if sth. goes wrong

doParse

public java.lang.String doParse(java.lang.String html,
                                java.lang.String encoding,
                                java.util.List noAutoCloseTags)
                         throws org.htmlparser.util.ParserException,
                                CmsException

Returns the result of subsequent parsing to the <cms:parse< tag implementation.

Parameters:

encoding - the encoding to use for parsing

html - the html content to parse

noAutoCloseTags - a list of upper case tag names for which parsing / visiting should not correct missing closing tags.

Returns:

the result of subsequent parsing to the <cms:parse< tag implementation

Throws:

org.htmlparser.util.ParserException - if something goes wrong at parsing

CmsException - if something goes wrong at accessing OpenCms core functionality

getCmsObject

protected CmsObject getCmsObject()

Returns the internal cms object for accessing core functionality.

This value will be initialized by the <cms:parse> tag.

Returns:

the internal cms object for accessing core functionality

getParam

protected java.lang.String getParam()

Returns the param.

Returns:

the param

getVisitor

protected I_CmsHtmlNodeVisitor getVisitor()

Returns the visitor.

Returns:

the visitor

setCmsObject

public void setCmsObject(CmsObject cmsObject)

Sets the internal cms object for accessing core functionality.

This will be invokde by the &tl;cms:parse> tag implementation.

Parameters:

cmsObject - the internal cms object for accessing core functionality to set

setParam

public void setParam(java.lang.String param)

The attribute value of the attribute param of the <cms:parse> tag.

Will be set by the <cms:parse> implementation.

Parameters:

param - the param to set
