Re: RELAX question re: required value

As a follow up, this may work for you:

<?xml version="1.0" encoding="UTF-8"?>
<grammar xmlns="http://relaxng.org/ns/structure/1.0">
    <start>
        <element name="root">
            <oneOrMore>
                <choice>
                    <element name="collection">
                        <value>all</value>
                    </element>
                    <zeroOrMore>
                        <element name="collection">
                            <text/>
                        </element>
                    </zeroOrMore>
                    <zeroOrMore>
                        <text/>
                    </zeroOrMore>
                </choice>
            </oneOrMore>
        </element>
    </start>
</grammar>

Hi Mike,

as far as I can see, there is no way to define this in RNG, since the same element or pattern cannot appear more than once in an interleave (see http://books.xmlschemata.org/relaxng/relax-CHP-6-SECT-9.html).

With choice it wouldn't be a problem (if I've understood your question correctly):

<?xml version="1.0" encoding="UTF-8"?>
<grammar xmlns="http://relaxng.org/ns/structure/1.0">
    <start>
        <element name="root">
            <choice>
                <element name="collection">
                    <value>all</value>
                </element>
                <zeroOrMore>
                    <element name="collection">
                        <text/>
                    </element>
                </zeroOrMore>
            </choice>
        </element>
    </start>
</grammar>

Best,

Maik

I have a schema that allows a bunch of different elements to be interleaved in any order; one of them is <collection>;  I want to require that a collection with value "all" be present, as well as allowing any number of other collections, in any order, using RELAX -- is that possible?  I can't seem to work out how, if it is.  For now I'm just using

element collection { text }+ &

Thanks

-Mike
