[XERCESC-1344] getElementById failure with attributes derived by restriction from xs::ID

• Type: Bug
• Status: Open

Description

Attributes derived by restriction as local simpleType from xs:ID (e.g. by restriction of the allowed ID-names to a predefined pattern) are correctly schema-validated as ID's (e.g., when 2 have the same name this is flagged as error), but are - as far as I can see - not added to DOMNodeIdMap. As a consequence, subsequent calls to getElementByID with these specific ID-names fails and returns null pointers.

Example:
<xs:attribute name="id" use="optional">
<xs:simpleType>
<xs:restriction base="xs:ID">
<xs:pattern value="P\d+"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>

Calls of getElementByID to elements with this ID attribute fail.

Removing the restriction:
<xs:attribute name="id" type="xs:ID" use="optional"/>

results in working getElementByID calls.

Although a minor issue, it leads to non-conformant behaviour and should be corrected at some stage.

Thanks,

Kris
