mapSafeElement

protected java.lang.String mapSafeElement(java.lang.String name)

Deprecated. Use the HtmlMapper mechanism to customize the HTML mapping. This method will be removed in Tika 1.0.

Maps "safe" HTML element names to semantic XHTML equivalents. If the given element is unknown or deemed unsafe for inclusion in the parse output, then this method returns null and the element will be ignored but the content inside it is still processed. See the isDiscardElement(String) method for a way to discard the entire contents of an element.

Subclasses can override this method to customize the default mapping.

Parameters:

name - HTML element name (upper case)

Returns:

XHTML element name (lower case), or null if the element is unsafe

Since:

Apache Tika 0.5

isDiscardElement

protected boolean isDiscardElement(java.lang.String name)

Deprecated. Use the HtmlMapper mechanism to customize the HTML mapping. This method will be removed in Tika 1.0.

Checks whether all content within the given HTML element should be discarded instead of including it in the parse output. Subclasses can override this method to customize the set of discarded elements.

Parameters:

name - HTML element name (upper case)

Returns:

true if content inside the named element should be ignored, false otherwise

Since:

Apache Tika 0.5

mapSafeAttribute

public java.lang.String mapSafeAttribute(java.lang.String elementName,
                                         java.lang.String attributeName)

Deprecated. Use the HtmlMapper mechanism to customize the HTML mapping. This method will be removed in Tika 1.0.
