Content model probs
Hi, I've being toying with a content model now and I think my brain must be overloaded because I can't think of the best way to format it so it'll parse. Basically I want to say that a tag should: 1. Contain #PCDATA, *OR* 2. an optional tag X followed by zero or more occurences of tag Y I had thought something like : (#PCDATA|(X?, Y*) but that doesn't seem to parse. At the moment I've had to settle on (#PCDATA|X|Y)* just so I can continue working, and manually check for the moment that I'm building documents which I consider legal. Any of you XML gurus got any suggestions? Thanks! L. p.s. A variation I'd also like to consider is changing the model such that 2. (above) becomes: 2. zero or more occurences of X, followed by zero or more occurences of Y. In this case X,Y can be interspersed. In the former, X *must* be before Y if its provided. ================================================================== "Never Do With More, What Can Be Achieved With Less" ---William of Occam ================================================================== Leigh Dodds Eml: ldodds@i... ingenta ltd Tel: +44 1225 826619 BUCS Building, University of Bath Fax: +44 1225 826283 ================================================================== xml-dev: A list for W3C XML Developers.
