You don't want to use "xml:id" ?
Here is the relaxNG trick (with a generic schema):
(tested with libxml 2.6.26)
<?php
$doc = new DOMDocument();
$doc->load(...);
$rng = '
<grammar xmlns="http://relaxng.org/ns/structure/1.0"
datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes">
<start>
<element>
<anyName/>
<ref name="anythingID"/>
</element>
</start>
<define name="anythingID">
<zeroOrMore>
<choice>
<element>
<anyName/>
<ref name="anythingID"/>
</element>
<attribute name="id">
<data type="ID"/>
</attribute>
<zeroOrMore>
<attribute><anyName/></attribute>
</zeroOrMore>
<text/>
</choice>
</zeroOrMore>
</define>
</grammar>
';
$doc->relaxNGValidateSource($rng);
var_dump($doc->getElementById('id1'));
?>
Note that ID values must be valid ones :
- integers do no work!
- @see http://www.w3.org/TR/REC-xml/#id
- => (Letter | '_' | ':') ( Letter | Digit | '.' | '-'
| '_' | ':' | CombiningChar | Extender )*
