Answer 1

Hi Arun,
In SAP PI, all the XML contents by default treated as STRINGS.
So if u want to check whether the incoming field is numeric or not... the only way is to write a UDF code for the same.
the UDF will be,
1. At first
import java.util.regex.Matcher;
import java.util.regex.Pattern;
in functions.
2.UDF content:
input: field,container
output:boolean
Code
boolean return_Value;
Pattern p = Pattern.compile("[0-9]*");          // If u are using the decimals please change the regular expression accordingly.
Matcher m = p.matcher(field);
if(m.matches())
retuen_Value = true;
else
return_Value = false;
return return_Value ;
I hope this will solve ur problem....
