Function: xmlSchemaCollapseString

xmlChar *	xmlSchemaCollapseString	(const xmlChar * value)

Removes and normalize white spaces in the string

value:a value
Returns:the new string or NULL if no change was required.

Function: xmlSchemaCompareValues

int	xmlSchemaCompareValues		(xmlSchemaValPtr x, 
					 xmlSchemaValPtr y)

Compare 2 values

x:a first value
y:a second value
Returns:-1 if x < y, 0 if x == y, 1 if x > y, 2 if x <> y, and -2 in case of error

Function: xmlSchemaFreeFacet

void	xmlSchemaFreeFacet		(xmlSchemaFacetPtr facet)

Deallocate a Schema Facet structure.

facet:a schema facet structure

Function: xmlSchemaFreeValue

void	xmlSchemaFreeValue		(xmlSchemaValPtr value)

Cleanup the default XML Schemas type library

value:the value to free

Function: xmlSchemaGetBuiltInListSimpleTypeItemType

xmlSchemaTypePtr	xmlSchemaGetBuiltInListSimpleTypeItemType	(xmlSchemaTypePtr type)

Lookup function

type:the built-in simple type.
Returns:the item type of @type as defined by the built-in datatype hierarchy of XML Schema Part 2: Datatypes, or NULL in case of an error.

Function: xmlSchemaGetBuiltInType

xmlSchemaTypePtr	xmlSchemaGetBuiltInType	(xmlSchemaValType type)

Gives you the type struct for a built-in type by its type id.

type:the type of the built in type
Returns:the type if found, NULL otherwise.

Function: xmlSchemaGetFacetValueAsULong

unsigned long	xmlSchemaGetFacetValueAsULong	(xmlSchemaFacetPtr facet)

Extract the value of a facet

facet:an schemas type facet
Returns:the value as a long

Function: xmlSchemaGetPredefinedType

xmlSchemaTypePtr	xmlSchemaGetPredefinedType	(const xmlChar * name, 
							 const xmlChar * ns)

Lookup a type in the default XML Schemas type library

name:the type name
ns:the URI of the namespace usually "http://www.w3.org/2001/XMLSchema"
Returns:the type if found, NULL otherwise

Function: xmlSchemaInitTypes

void	xmlSchemaInitTypes		(void)

Initialize the default XML Schemas type library

Function: xmlSchemaIsBuiltInTypeFacet

int	xmlSchemaIsBuiltInTypeFacet	(xmlSchemaTypePtr type, 
					 int facetType)

Evaluates if a specific facet can be used in conjunction with a type.

type:the built-in type
facetType:the facet type
Returns:1 if the facet can be used with the given built-in type, 0 otherwise and -1 in case the type is not a built-in type.

Function: xmlSchemaNewFacet

xmlSchemaFacetPtr	xmlSchemaNewFacet	(void)

Allocate a new Facet structure.

Returns:the newly allocated structure or NULL in case or error

Function: xmlSchemaValPredefTypeNode

int	xmlSchemaValPredefTypeNode	(xmlSchemaTypePtr type, 
					 const xmlChar * value, 
					 xmlSchemaValPtr * val, 
					 xmlNodePtr node)

Check that a value conforms to the lexical space of the predefined type. if true a value is computed and returned in @val.

type:the predefined type
value:the value to check
val:the return computed value
node:the node containing the value
Returns:0 if this validates, a positive error code number otherwise and -1 in case of internal or API error.

Function: xmlSchemaValPredefTypeNodeNoNorm

int	xmlSchemaValPredefTypeNodeNoNorm	(xmlSchemaTypePtr type, 
						 const xmlChar * value, 
						 xmlSchemaValPtr * val, 
						 xmlNodePtr node)

Check that a value conforms to the lexical space of the predefined type. if true a value is computed and returned in @val. This one does apply any normalization to the value.

type:the predefined type
value:the value to check
val:the return computed value
node:the node containing the value
Returns:0 if this validates, a positive error code number otherwise and -1 in case of internal or API error.

Function: xmlSchemaValidateFacet

int	xmlSchemaValidateFacet		(xmlSchemaTypePtr base, 
					 xmlSchemaFacetPtr facet, 
					 const xmlChar * value, 
					 xmlSchemaValPtr val)

Check a value against a facet condition

base:the base type
facet:the facet to check
value:the lexical repr of the value to validate
val:the precomputed value
Returns:0 if the element is schemas valid, a positive error code number otherwise and -1 in case of internal or API error.

Function: xmlSchemaValidateLengthFacet

int	xmlSchemaValidateLengthFacet	(xmlSchemaTypePtr type, 
					 xmlSchemaFacetPtr facet, 
					 const xmlChar * value, 
					 xmlSchemaValPtr val, 
					 unsigned long * length)

Checka a value against a "length", "minLength" and "maxLength" facet; sets @length to the computed length of @value.

type:the built-in type
facet:the facet to check
value:the lexical repr. of the value to be validated
val:the precomputed value
length:the actual length of the value
Returns:0 if the value is valid, a positive error code otherwise and -1 in case of an internal or API error.

Function: xmlSchemaValidateListSimpleTypeFacet

int	xmlSchemaValidateListSimpleTypeFacet	(xmlSchemaFacetPtr facet, 
						 const xmlChar * value, 
						 unsigned long actualLen, 
						 unsigned long * expectedLen)

Checks the value of a list simple type against a facet.

facet:the facet to check
value:the lexical repr of the value to validate
actualLen:the number of list items
expectedLen:the resulting expected number of list items
Returns:0 if the value is valid, a positive error code number otherwise and -1 in case of an internal error.

Function: xmlSchemaValidatePredefinedType

int	xmlSchemaValidatePredefinedType	(xmlSchemaTypePtr type, 
					 const xmlChar * value, 
					 xmlSchemaValPtr * val)
