But I'd like to use this (doesn't validate with the xml) (in mysql.xsd): <
xs:complexType name=
"table">
<
xs:sequence>
<
xs:element name=
"field" type=
"mysql:field" minOccurs=
"0" maxOccurs=
"unbounded" />
</
xs:sequence>
<
xs:attribute name=
"name" type=
"xs:string" use=
"required" />
</
xs:complexType>
[..]
<
xs:complexType name=
"field">
<
xs:attribute name=
"name" type=
"xs:string" use=
"required" />
<
xs:attribute name=
"table" type=
"xs:string" use=
"optional" />
</
xs:complexType>This is probably the only way out, if I'm trying to extend using the same tagname (but stronger validation because of parent element). This doesnt work (in mysql.xsd): <
xs:complexType name=
"cond">
<
xs:sequence>
<
xs:element name=
"field" minOccurs=
"0" maxOccurs=
"unbounded">
<
xs:complexType>
<
xs:complexContent>
<
xs:extension base=
"field">
<
xs:attribute name=
"operator" type=
"xs:string" use=
"required" />
</
xs:extension>
</
xs:complexContent>
</
xs:complexType>
</
xs:element>
</
xs:sequence>
</
xs:complexType>I don't understand what I'm doing wrong, because all google code snippets + w3 works does say this should be right. I've been shuffling around with targetnamespace and so on, but it didn't work outThis error i get very much:Warning: DOMDocument::schemaValidate() [
function.DOMDocument-schemaValidate]: Validation failed: no DTD found !Element '{http://sove.nl/ns/system/mysql/}field': This element is not expected. Expected is ( field ). in /var/www/client/sove.nl/httpdocs/xmysql_mysql.php on line 34So it's expecting an element with a blank namespace, but it's defined inside the MYSQL namespace (but is ignored)How can I get my extension to work? Please help, been trying for days now. Big thanks, Robert de Wilde Here are my full source codes (better don't quote them i guess): XMYSQL_MYSQL.PHP<?php $library = new SchemaDOMDocument("1.0");

if (! $schemaLocation) {
throw new DOMException('No schemas found');
}
