XML DTD Issues

[TheJoey]

Im having problems getting my dtd to work

i want the user to have a option like

<!ELEMENT option (choose)

<!ELEMENT choose (one|two|three) >

 

But it doesnt seem to like it because my whole dtd works without that line.

im completely stuck!

Thanks in advance for any help i can get

How is this related to PHP?

[TheJoey]

Couldnt find a forum for it to suit, and considering that php is loading my xml thought it would be ok.

<!ELEMENT option (choose)><!-- you forgot > -->

<!ELEMENT choose (one|two|three) >

[TheJoey]

What does that acutally do?

 

ive tried alot of things, it parses fine, although i want it to only accept the values option1-3

<!DOCTYPE root SYSTEM "root.dtd">
<root>
<option>
dsfsdf
</option>
</root>

root.dtd

<!ELEMENT root (option)>
<!ELEMENT option (#PCDATA)>
<!ATTLIST option
option (option1|option2) "option1" >

What do you exactly want to do?

[TheJoey]

i only want it to parse. if ethier option1 option2 option3

 

is selected or it will give me a error saying must be option1 - 3

 

etc

is that possible with dtd?

[ignace]

Can you give me an example XML because I don't understand what you mean besides I think your DTD is wrong and should be:

 

<!ELEMENT root (option1|option2|option3)>
<!ELEMENT option1 (#PCDATA)>
<!ELEMENT option2 (#PCDATA)>
<!ELEMENT option3 (#PCDATA)>

 

The following is all valid

 

<root>
    <option1></option1>
</root>

<root>
    <option2></option2>
</root>

<root>
    <option3></option3>
</root>

 

This code is invalid

 

<root>
    <option1></option1>
    <option2></option2>
    <option3></option3>
</root>

[TheJoey]

Is there a way to restrict the data that goes "inside" those <option> </option>

 

<option> This here </option> "this here being the data we want to restrict for example to male or female"

[ignace]

No but you can do:

 

<!ATTLIST option sex (male|female) #REQUIRED>

[TheJoey]

That would make it so

 

<option sex="male" />

right?
