check if input value is Date

sbutt · May 3rd, 2011, 09:02 AM

Hi Folks,
I am trying to implement a script where I want to check if the input value has date string in it or not. For example:

Code:

<ota:Caution ID="Alternative" Type="PackageDetail">Room</ota:Caution>

And

Code:

 

<ota:Caution ID="Alternative" Type="PackageDetail">2011-11-12</ota:Caution>

In the first example, the Caution element has value as "Room", which is not a date, hence the method should return false, otherwise true, as in case of example 2nd.

Any help please?

Assuming this is XSLT 2.0, use

Code:

ota:Caution castable as xs:date

I am using xslt 1.0. Any help in that?

You have my deep sympathy. Is it really impossible to move forward?

Unless you use extension functions (which are processor dependent), it's going to be fairly hard work. But it can be done. Check that the string-length is 10; use translate to strip the hyphens and check that string(number(x)) is not equal to "NaN"; use substring() to check that the characters in positions 5 and 8 are hyphens.
