escape

public static java.lang.String escape(java.lang.String text)

Escapes invalid XML characters in the given character data using XML entities. For the moment, only the following characters are being escaped: (<), (&), (') and (").

Parameters:

text - the character data to escape

Returns:

the escaped character data
