String Validation Using XSLT

elango271986 · June 21st, 2013, 08:26 AM

I have some requirement which should validate the string. My requirement is:

1. if the given string length is less than 5, throw an error.
2. if the string is longer than 5, then break the string into substrings of length of 6. Test the Substring.
-> the substring last value should end with ; or |. i.e., 6th character.
-> if the value at position 0 or 4 are a whitespace throw an error.
-> if the value at position 0 thru 4 is something other than alphanumeric character or whitespace or '@' symbol, throw an error.
if there are more substring, repeat the process.

How to obtain this.
sample xml file is:

Code:

<sample>
<row>
   <comment>
      <value>ABCDE</value>
   </comment>
</row>
<row>
   <comment>
      <value>ABCDE;ABCDE</value>
   </comment>
</row>
</sample>

if u need more info, kindly let me know.

First, it makes a big difference whether you are using XSLT 1.0 or 2.0 - you need to say.

Secondly, please don't just ask people to write the code for you. You need to explain what you have tried and where you got stuck. I'm here to help you solve the problem, not to present you with the solution on a plate, and I can't help you solve it if I have no idea why you are finding it difficult.

I did the above validation step in the javascript. It is working fine. I dont know know how to implement the same in xml.

Then read my book, and tell me which parts you don't understand.

You'll want to understand functions such as concat(), substring(), tokenize() etc and perhaps xsl:analyze-string.
