Re: [xml-dev] Problem with Entity parameter

Hi, Sandor,

 

I am actrually still a bit confused by the use of PCDATA.

 

If I have the segment in a XML like:

<graph>it is a graph<n>sky</n>you can see it on<img>a link</img>nice</graph>

so by using a element container for the PCDATA, it is like:

 

So compared with the first solution (<!ELEMENT Graph (#PCDATA|n|img)*>), the benifit for your solution is that in the XML, I can have any kind of combinations among the children elements by wrapping the text by a pair of tags (<text> and <\text>), right?  

Thank you,

Rita

hi Rita - you could try creating an element container for the pcdata, for example:

 

<!ELEMENT text (#PCDATA)>

 

then your graph element might look something like this:

 

<!ELEMENT graph ( text*, (n,text*)?, (img, text))>

 

hope this helps.

 

later,

Hi, Bjoern,

 

Thanks for your reply! What shuld I do if I want to limit the exact accurrance for each sub-element in the element Gragh? I mean I want to have:

0 or more "PCDATA" and "n" but 1 or more "img" in it.

 

Cheers,

syt
<!ELEMENT Graph (#PCDATA|n|img)*>

If you have mixed content you only constrain which child elements are
allowed, not the order in which they have to occur or their number:

<!ELEMENT Graph (#PCDATA|n|img)*>

See http://www.w3.org/TR/xml/#sec-mixed-content for more information.
