Length Post-processing Function can be used to get the length of the value in our extracted field result. For example, I have this scraping agent “Length Function Example(Post-Processing)” in my account and I want to get the length of product field Name for some internal use. So, We can use the Length Post-Processing Function to get the characters length in particular field.
Before
Steps
-
Add a new field name something like I did, field Name Length and selector will be same as for product field Name
-
Now, Click on the
Add Post-Processingbutton to add theLengthPost-Processing function, The below dialog box will appear -
There is no parameter requires in this function, so just adding this is enough
-

Savethe function and the scraping agent configuration -
And finally re-run you agent to apply the changes.

Now,if we look the updated result, we have a length of product Name in a new field called Name Length where we can see the actual number of characters in this field.
