Package org.apache.jackrabbit.vault.util.xml.serialize

Class NormalizingSaxFilter

java.lang.Object

org.xml.sax.helpers.XMLFilterImpl

org.apache.jackrabbit.vault.util.xml.serialize.NormalizingSaxFilter

All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler, LexicalHandler, XMLFilter, XMLReader

public class NormalizingSaxFilter
extends XMLFilterImpl
implements LexicalHandler

SAX filter which

1. orders attributes alphabetically
2. strips ignorable whitespace (works even without schema/DTD: all characters in FileVault can be stripped because all elements are supposed to be empty)
3. removes leading comments (prior to root element) due to bug in SAX2StAXStreamWriter in Java
