Choice

[RwDwR]

I have just started using XML, but among many things I have to do the following:

Within my xml file I have the need for a name tag that can exist in two ways:

1. <Name>John Doe</Name>
2. <Name>
     <First>John</First>
     <Last>Doe</Last>
   </Name>

It must be one or the other, how can I declare this using an XML-Schema??
I think the problem lies in the first option being a simple type, and the second a complex type...

Well, any help would be great, thanks

This seams to give me the effect I want, but I am not happy about it:

<xs:element name=&quot;name&quot;>
 <xs:complexType mixed=&quot;true&quot;>
   <xs:choice>
   <xs:any minOccurs=&quot;0&quot; maxOccurs=&quot;1&quot;></xs:any>
   <xs:sequence>
    <xs:element ref=&quot;first&quot;/>
    <xs:element ref=&quot;last&quot;/>
   </xs:sequence>
  </xs:choice>
 </xs:complexType>
</xs:element>

The problem is that the any tag allows, well, litteraly any one thing, wheter that be tags or text, and I only want to allow text, any ideas?

I am not sure you can have that... A cleaner approach would be to define two types for each form you have and have a &quot;personName&quot; complex type that would make use of choices for each type. However, in this case, you will notice below in the <PersonName> type that you cannot have the same <name> element for both choices, as it is considered inconsistent and illegal by many parsers.

<xs:complexType name=&quot;SName&quot;>
<xs:simpleContent>
<xs:extension base=&quot;xs:string&quot;/>
</xs:simpleContent>
</xs:complexType>
<xs:complexType name=&quot;CName&quot;>
<xs:sequence>
<xs:element name=&quot;First&quot;/>
<xs:element name=&quot;Last&quot;/>
</xs:sequence>
</xs:complexType>
<xs:complexType name=&quot;PersonName&quot;>
<xs:choice>
<xs:element name=&quot;SepName&quot; type=&quot;CName&quot;/>
<xs:element name=&quot;SimpleName&quot; type=&quot;SName&quot;></xs:element>
</xs:choice>
</xs:complexType>

You know, I really hate these languages that say they are good on every aspect, and stuff, I can't even declare such a simple thing like this?? The thread you put on the bottom does work, but it allows text to be present togheter with the tags, I'll go for my any tag for now, and hope nobody finds out

Remember: XML is extensible. If you dont like it, extend it :0)
