public class XSAttributeChecker

extends java.lang.Object

Class XSAttributeCheck is used to check the validity of attributes appearing in the schema document. It - reports an error for invalid element (invalid namespace, invalid name) - reports an error for invalid attribute (invalid namespace, invalid name) - reports an error for invalid attribute value - return compiled values for attriute values - provide default value for missing optional attributes - provide default value for incorrect attribute values But it's the caller's responsibility to check whether a required attribute is present. Things need revisiting: - Whether to return non-schema attributes/values - Do we need to update NamespaceScope and ErrorReporter when reset()? - Should have the datatype validators return compiled value - use symbol table instead of many hashtables

INTERNAL:

Usage of this class is not supported. It may be altered or removed at any time.

checkAttributes

public java.lang.Object[] checkAttributes(org.w3c.dom.Element element,
                                          boolean isGlobal,
                                          org.apache.xerces.impl.xs.traversers.XSDocumentInfo schemaDoc)

Check whether the specified element conforms to the attributes restriction an array of attribute values is returned. the caller must call returnAttrArray to return that array.

Parameters:

element - which element to check

isGlobal - whether a child of <schema> or <redefine>

schemaDoc - the document where the element lives in

Returns:

an array containing attribute values

checkAttributes

public java.lang.Object[] checkAttributes(org.w3c.dom.Element element,
                                          boolean isGlobal,

                                          boolean enumAsQName)

Check whether the specified element conforms to the attributes restriction an array of attribute values is returned. the caller must call returnAttrArray to return that array. This method also takes an extra parameter: if the element is "enumeration", whether to make a copy of the namespace context, so that the value can be resolved as a QName later.

Parameters:

element - which element to check

isGlobal - whether a child of <schema> or <redefine>

schemaDoc - the document where the element lives in

enumAsQName - whether to tread enumeration value as QName

Returns:

an array containing attribute values
