XML::Compile::Schema::Instance - Represents one schema


 # Used internally by XML::Compile::Schema
 my $schema = XML::Compile::Schema::Instance->new($xml);


This module collect information from one schema, and helps to process it.



$obj->new(TOP, OPTIONS)

Get's the top of an XML::LibXML tree, which must be a schema element. The tree is parsed: the information collected.

 Option                --Default
 attribute_form_default  <undef>
 element_form_default    <undef>
 filename                undef
 source                  undef
 target_namespace        <undef>

. attribute_form_default => 'qualified'|'unqualified'

. element_form_default => 'qualified'|'unqualified'

Overrule the default as found in the schema. Many old schemas (like WSDL11 and SOAP11) do not specify the default in the schema but only in the text.

. filename => FILENAME

When the source is some file, this is its name.

. source => STRING

An indication where this information came from.

. target_namespace => NAMESPACE

Overrule or set the target namespace.



Returns a list of all defined attribute groups.


Returns a lost of all globally defined attribute names.


Returns a list with all complexType names.


Returns one global element definition.


Returns a list of all globally defined element names.



Returns a list of all defined model groups.





Returns a HASH with the base-type as key and an ARRAY of types which extend it.


Returns a list with all simpleType names.




A schema can defined more than one target namespace, where recent schema spec changes provide a targetNamespace attribute.


Returns the type definition with the specified name.


Returns a list of all simpleTypes and complexTypes


$obj->find(KIND, FULLNAME)

Returns the definition for the object of KIND, with FULLNAME.

example: of find

  my $attr = $instance->find(attribute => '{myns}my_global_attr');


Returns a list of all schemaLocations specified with the import NAMESPACE (one of the values returned by imports()).


Returns a list with all namespaces which need to be imported.


Returns a list of all schemaLocations which where specified with include statements.

$obj->printIndex([FILEHANDLE], OPTIONS)

Prints an overview over the defined objects within this schema to the selected FILEHANDLE.

 Option       --Default
 kinds          <all>
 list_abstract  <true>

. kinds => KIND|ARRAY-of-KIND

Which KIND of definitions would you like to see. Pick from element, attribute, simpleType, complexType, attributeGroup, and group.

. list_abstract => BOOLEAN

Show abstract elements, or skip them (because they cannot be instantiated anyway).
