Previous Comments: ------------------------------------------------------------------------ [2021-04-08 16:15:06] cmb@php.net This is likely a libxml2 issue which apparently has been fixed in the meantime; the script works as expected with libxml2 2.9.10. Or do you still experience this issue with any of the actively supported PHP versions[1]? If so, what's your libxml2 version?

Test script: --------------- Code: $xdoc = new DomDocument; $xdoc->loadXML( file_get_contents( 'xml.xml' ) ); $xdoc->schemaValidate( 'schema.xsd' ); Schema, schema.xsd: <?xml version="1.0" encoding="utf-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="a"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:pattern value=".(\.{0,1}){0}@"></xs:pattern> </xs:restriction> </xs:simpleType> </xs:element> </xs:schema> xml.xml: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <a>x@</a> Expected result: ---------------- Validation expected. Actual result: -------------- Warning: DOMDocument::schemaValidate(): Element 'a': [facet 'pattern'] The value 'x@' is not accepted by the pattern '.(\.{0,1}){0}@'. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63942&edit=1
