i have HSN field and some times those are having special characters, if it is not having any special character and it having single special character no need to select.
But here which string having more than one special character then select.
Special characters: /-
HSN1-11-11-11/22/21-2/21/2-2/2
In above table i need to select on yellow highlighted data only \\

I would use the StringLengthCalculator to calculate the original length of the string.
Then use a StringReplacer to remove all special characters.
Repeat the StringLengthCalculator and use an AttributeCretator to calculate the difference in length.
That will tell you the number of special characters.
Could also be done in one AttributeCreator using string functions like StringLength and ReplaceString in the Text Editor.
+19Hi @tomjerry.vl,
Please use a StringSearcher with the expression '[/-]' and Advanced - All Matches List Name set to '_matches'. THis will create a list of all the special character matches in the string.
Next, we want to find the features with more than one element in the list, which we can do with a ListElementCounter on the _matches{} list. Use a Tester afterwards to find _element_count > 1.

ok but too lengthy process

To use just the one transformer (AttributeCreator) you can use this logic:
It will calculate the number of - and / characters in the test string.

yes it working
Here is an alternative that uses only one transformer with a regular expression:
Using a StringSearcher, paste the following Regular Expression to match your cases:
[-\\/].*[-\\/]
This will output your required features in the Matched port.

ok but in fme 2017.1 version ListElementCounter parameters no list attribute available how to resolve this issue please tell me

Clicking on the triangle beside Advanced in the transformer settings should expose the list entries for you.

I have used this expression " @StringLength(@Value(housenumbe))-@StringLength(@ReplaceRegEx(@Value(housenumbe),[-/],,true)) "
then output result is shown below
5-4
3-2
6-4
5-3
9-6
I want total subtraction value
like this
1
1
2
2
3
please tell me sir

To do the math, you will need the @Evaluate() function.
+17If an attribute contains the value 5-4 and you need it to be 1, you can use the ExpressionEvaluator transformer to do the math.
Hope this helps.
