How do I set maxLength of a string on an xforms template

harrymoore — Tue, 20 Feb 2007 23:21:47 GMT

Simple question: how do I set a limit on the lenth of an input string?I found an example somewhere that showed how to use an xs:restriction but this does not appear to work:<xs:simpleType name="string25"> <xs:restriction base="xs:normalizedString"> <xs:maxLength value="25"/

i'll take a look at this - but the xforms processor should be validating the user entered string length against the schema and reporting it invalid if it's not valid. are you looking for more of a ui side change? do you want the textfield itself to be x chars long - because that's not implemented yet.

i don't really care, yet, about the size of the field on the form but i'm deploying the value to a database field VARCHAR(25) so I want to limit the input size of the field to 25 chars. How do I do that?

Thanks,

hmmm…. it looks like my xforms processor is not validating schema simple types rigorously. i'll see if there's a switch that needs turning on - but it's possible that all these restrictions need to be turned into xforms constraints in order to get this to work which would be rather annoying.

So am I doing the right thing by "subclassing" the xs:normalizedString this way? Is this a best practice? I'm having trouble finding good docs/tutorials on xsd, xforms to know. I just stumbled upon this solution.

maxLength or length restrictions are the way to go. in the next version these restrictions will be enforced by textfields at a minimum - and hopefully by the xforms processor if i can figure out how to get it to properly validate schema types consistently.
