Question: is this possible in XML?

[joey mo]

Hey guys new to these forums.

just wondering if its possible to restrict the "input" of a xml field.

for example

<root>
<option>
testing (i want to restrict this so only option1 or option2 will parse)
</option>


Testing is what i want to restrict, i know there a ways to restrict the value and type of a attribute but this isnt what im wanting to do

thanks for any help!

Something like this?

<xsd:complexType name="optionType">
    <xsd:simpleContent>
      <xsd:restriction base="xsd:string">
			<xsd:enumeration value="Testing"/>
			<xsd:enumeration value="SomeOtherTesting"/>
      </xsd:restriction>
    </xsd:simpleContent>
</xsd:complexType>

Yes but instead of using a schema i want to only use a DTD

or eqaully efficient in DTD XML

i want to only use a DTD

Why? DTDs can't do anything like this.

Ok thanks guys, so the only way i can do anything close in dtd is so store information in the attributes? like type=option1 etc?

I'm not sure what you mean by "close", or even what you meant by that example. Perhaps you ought to clarify your requirement so we could have a practical discussion about it.

I dont know how i can explain it better then in the first post.

between <option>(This space here) </option> the only values i want accepted are the ones i choose so for example male or female. i need someway to do that without a schema.

i know its possible to give the attribute a name, but ive been told it is possible with the <!ELEMENET option (male|female)* >

I understood the first post. But then you changed your mind to want something "close". I didn't understand that part.

Anyway, as Ulf already said, DTDs can't do anything like that. But it might be a good idea for you to read a DTD tutorial. Like this one for example. By the time you get to the end of it you should have a better understanding of both DTDs and XMLs. That can only be a good thing.
