The RegexSplit attribute definition produces its values by applying a Java regular expression to each of the input attribute's values.  For every input value that matches, the first match group is added as a new output value.

Schema Name and Location

This xsi:type is defined in the urn:mace:shibboleth:2.0:resolver namespace 3.3, the schema for which can be located at http://shibboleth.net/schema/idp/shibboleth-attribute-resolver.xsd

Prior to V3.3 supplied plugins were defined by a schema type in the urn:mace:shibboleth:2.0:resolver:ad namespace, the schema for which is located at http://shibboleth.net/schema/idp/shibboleth-attribute-resolver-ad.xsd. This is still supported, but every element or type in the old namespace has an equivalently named (but not necessarily identical) version in the urn:mace:shibboleth:2.0:resolver namespace. The use of the urn:mace:shibboleth:2.0:resolver namespace also allows a relaxation of the ordering requirements of child elements to reduce strictness.

Attributes

Any of the common attributes can be specified. In addition, the following attributes are defined:

NameTypeReq?DefaultDescription
regex
stringY
Provides the regular expression to apply
caseSensitive
boolean
falseWhether the match is case sensitive or not

Child Elements

Any of the common child elements can be specified.

Example

<AttributeDefinition id="exampleRegexp" xsi:type="RegexSplit" regex="Pre-(.+)-Post">
	<InputDataConnector ref="myLDAP" attributeNames="uid" />
	<AttributeEncoder xsi:type="SAML2String" name="http://example.org/example" friendlyName="regexp"/>
</AttributeDefinition>

If this definition was supplied with an attribute with the input values "Fred", "Pre-And-Post", it would produce an output attribute with one value "And".
