Re: [xml-dev] XSD Validating unknown number of attributes from 1 to N

[Michael Kay <mike@saxonica.com>]

This is a very bizarre XML design, and XSD is not designed to enable validation of bizarre XML designs.

It can of course be done using XSD 1.1 assertions: something like

<xs:assert test="every $a in $value/@* satisfies name($a) = 'id' or name($a) = 'link1' or 

   (matches(name($a), 'link[0-9]+' and exists($value/@*[name() = concat('link', number(substring-after(name($a), 'link'))-1)))"/>

Hi!

I need to validate the following xml structure:

...

<element id="1" link1="xyz" link2="xyzz" />

...

There can be from link1 attr to anyone desired.

How could I achieve that using XSD?

Best regards!
