XMLSchema problem with XML document

[Samjiman]

Hello. I have this XML document:


<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<vbtagsconf xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="vbtags.xsd">

<vbtag name="bold" params="false" group="basic">
<regexp>\[/?b]</regexp>
<code>&lt;b&gt;</code>
</vbtag>
<vbtag name="italic" params="false" group="basic">
<regexp>\[/?i]</regexp>
<code>&lt;i&gt;</code>
</vbtag>

</vbtagsconf>


I have this XMLSchema:


<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<!-- root element -->
<xs:element name="vbtagsconf">
<xs:complexType>
<xs:sequence minOccurs="1" maxOccurs="unbounded">
<!-- first tag with three attributes -->
<xs:element name="vbtag">
<xs:complexType>
<xs:attribute name="name" type="xs:string"/>
<xs:attribute name="params" type="xs:string"/>
<xs:attribute name="group" type="xs:string"/>
</xs:complexType>
</xs:element>
<!-- next two tags with no attributes -->
<xs:element name="regexp" type="xs:string"/>
<xs:element name="code" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>


When I validate the document against the schema, I get this error message:
"No character data is allowed by content model". What does that mean? What have I done wrong?

Thanks in advance.

I have some experience with XML and Oracle DBMS, probably there is some technical difference between characters and strings.

Or also there code sum Unicode, non-Unicode character problem. It depends on what is specified in XML file header i.e. <?xml> tag.

I gave up eventually and stuck to a DTD. Proper validation of data isn't really necessary for this project I'm working on anyway.

Thanks anyway. :)
