UDF mapping to split string

Question

Hi,
I'm starting with UDF functions.
How can i split source string at '-' and take first part into target.
ex : 123-456 -> 123
Easy points for those who know...
Thanks in advance,
Laurent.

Hi Laurent,
Use an Advanced User Defined Function. Adavnced user Defined Functions can return Multiple values.
UDF1:
1.Takes renmark as input.
2.Does the split on the basis of ;
3. Splits each split of step 2 on the basis of /
4. Add the output of step 3 to the resultlist with a context change.
UDF2:
1.Takes renmark as input.
2.Does the split on the basis of ;
3. Splits each split of step 2 on the basis of /
4. Add the output of step 3 to the resultlist with a context change.
For Advanced UDF's,

You can try this piece of code in your mapping...
You need 3 UDFs each for <detail>, <field1>,<field2>
UDF1: For <detail>
String arr[] = a[0].split(";");
for (int i=0;i<arr.length;i++)
result.addValue(arr);
UDF2: For ><field1>
String str = a[0];
String str1 = null;
String sarr1[] = str.split(";");
for (int i=0; i<sarr1.length;i++)
str1 = sarr1;
String sarr2[] = str1.split("/");
for (int j=0; j><sarr2.length;j++){
result.addValue(sarr2[j]);
j++;
result.addContextChange();
UDF2: For ><field2>
String str = a[0];
String str1 = null;
String sarr1[] = str.split(";");
for (int i=0; i<sarr1.length;i++)
str1 = sarr1;
String sarr2[] = str1.split("/");
for (int j=0; j><sarr2.length;j++){
j++;
result.addValue(sarr2[j]);
result.addContextChange();
..All these functions requires one input <remark>
Hope this helps you ..
