Validation

Hi

Is it possible to validate a field using Reg Exp In Orbeon?

for ex. I want to validate a field that should not take 999
for that i will use (?!9{3})([0-9]{3})

but is it possible to use reg exp in orbeon

Hi Bharamani,

You can use the XPath matches() functions:

matches(., 'your regexp')

Note that the `.` refers the value of the current field.

Hi

At this point

 matches(., '(?!9{3})([0-9]{3})')

This is not working.

Any other way from your end

Thanks

Hi Bharamani,

The matches() in XPath doesn't support negative lookahead, per the specification, so you can't use this syntax. But since this is XPath, I think you would gain anyway at writing the expression as:

matches(., '[0-9]{3}') and . != '999'
