Method Detail

includeDocType

public boolean includeDocType()

Description copied from interface: StAXFilter

The current event is a DocType event.

Specified by:

includeDocType in interface StAXFilter

Returns:

true if the DocType should become a JDOM Fragment.

includeElement

public boolean includeElement(int depth,
                     java.lang.String name,
                     Namespace ns)

Description copied from interface: StAXFilter

The current event is an Element event.

If the return value of this call is true, then this Element will be processed as a JDOM fragment. You may then get calls to the prune* methods to determine whether child content of this Element should be pruned.

Specified by:

includeElement in interface StAXFilter

Parameters:

depth - The depth of this content from the document root (the root Element is at depth 0)

name - The XML tag name of this Element

ns - The Namespace of this Element

Returns:

true if the Element should become a JDOM Fragment.

includeComment

public java.lang.String includeComment(int depth,
                              java.lang.String comment)

Description copied from interface: StAXFilter

The current event is a Comment event.

A null return value will cause the Comment to be ignored, and a non-null return value will become the Comment's text.

To include the comment as-is, do:

 public String includeComment(int depth, String comment) {
     return comment;
 }
 

Specified by:

includeComment in interface StAXFilter

Parameters:

comment - The Comment value

Returns:

null if you want to exclude this comment, or a non-null value which will become the new comment value.
