XML::Parser::ContentModel Methods

The element declaration handlers are passed objects of this class as the content model of the element declaration. They also represent content particles, which are components of a content model.

When referred to as a string, these objects are automatically converted to a string representation of the model (or content particle):

• isempty
• Returns true if the object is EMPTY, false otherwise.
• isany
• Returns true if the object is ANY, false otherwise.
• ismixed
• Returns true if the object is (#PCDATA) or (#PCDATA|...)*, false otherwise.
• isname
• Returns true if the object is an element name.
• ischoice
• Returns true if the object is a choice of content particles.
• isseq
• Returns true if the object is a sequence of content particles.
• quant
• Returns undef or a string representing the quantifier (?, *, +) associated with the model or particle.
• children
• Returns undef or (for mixed, choice, and sequence types) an array of component content particles. There will always be at least one component for choices and sequences, but for a mixed content model of pure PCDATA, (#PCDATA), then undef is returned.
