java.lang.String getConfiguration()

Returns the configuartion String of this visitor or the empty String if was not provided before.

getResult

java.lang.String getResult()

Returns the text extraction result.

返回:

the text extraction result

process

java.lang.String process(java.lang.String html,
                         java.lang.String encoding)
                  throws org.htmlparser.util.ParserException

Extracts the text from the given html content, assuming the given html encoding.

参数:

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

setConfiguration

void setConfiguration(java.lang.String configuration)

Set a configuartion String for this visitor.

This will most likely be done with data from an xsd, custom jsp tag, ...

参数:

configuration - the configuration of this visitor to set.

setNoAutoCloseTags

void setNoAutoCloseTags(java.util.List noAutoCloseTags)

Sets a list of upper case tag names for which parsing / visitng should not correct missing closing tags.

This has to be used before process(String, String) is invoked to take an effect.

参数:

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

visitEndTag

void visitEndTag(org.htmlparser.Tag tag)

visitRemarkNode

void visitRemarkNode(org.htmlparser.Remark remark)

Visitor method (callback) invoked when a remark Tag (HTML comment) is encountered.

参数:

remark - the remark Tag to visit.

visitStringNode

void visitStringNode(org.htmlparser.Text text)

Visitor method (callback) invoked when a remark Tag (HTML comment) is encountered.

参数:

text - the text that is visited.
