[xml] Warning: complex type 'type_subelement': The content model is not determinist.

["Wetzler, Thomas" <thomas wetzler siemens com>]

Hi there,

 

I've developed a schema-definition with the tool "XML-Spy" on my workstation. It works fine without any failures:

 

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
        <xs:attributeGroup name="controlsequences">
                <xs:attribute name="pre" type="xs:string"/>
                <xs:attribute name="post" type="xs:string"/>
        </xs:attributeGroup>
        <xs:complexType name="type_subelement">
                <xs:choice>
                        <xs:sequence>
                                <xs:element name="header" type="columns" fixed="AN"/>
                                <xs:element name="content" type="type_an"/>
                        </xs:sequence>
                        <xs:sequence>
                                <xs:element name="header" type="columns" fixed="PN"/>
                                <xs:element name="content" type="type_pn"/>
                        </xs:sequence>

                </xs:choice>
        </xs:complexType>
        <xs:simpleType name="columns">
                <xs:restriction base="xs:string">
                        <xs:enumeration value="AN"/>
                        <xs:enumeration value="PN"/>

               </xs:restriction>
        </xs:simpleType>
        <xs:simpleType name="type_an">
                <xs:restriction base="xs:string">
                        <xs:maxLength value="80"/>
                </xs:restriction>
        </xs:simpleType>
        <xs:simpleType name="type_pn">
                <xs:restriction base="xs:string">
                        <xs:maxLength value="1600"/>
                </xs:restriction>
        </xs:simpleType>

      <xs:element name="subelement" type="type_subelement"/>
        <xs:element name="element">
                <xs:complexType>
                        <xs:sequence>
                                <xs:element ref="subelement" maxOccurs="unbounded"/>
                        </xs:sequence>
                </xs:complexType>
        </xs:element>
</xs:schema>

 

I like to user this XML-Schema within a PHP5.0.4-programm with libxml2-2.6.20 to check incoming data. When I try to check the data, the parser complains

 

Warning: complex type 'type_subelement': The content model is not determinist. in /wir/searchservertest/src/load_db/xml_parser/FtcinCreator.php on line 37

 

Warning: Invalid Schema in /wir/searchservertest/src/load_db/xml_parser/FtcinCreator.php on line 37
Validate FAILED

The library seems to have difficulties with the <xs:choice><xs:sequence> combination. XML-Spy has no problem with that.

Does anyone have an idear?

 

Thanks
