Regex Post-processing function can be used to extract the string in our extracted field result. For example, I have this scraping agent “Regex Function Example(Post-Processing)” in my account and I want to extract state from City field. Here, we can use the
Regex Post-processing function to extract the state from City field.
Edit the scraping agent by clicking on the Edit tab.
Add a new field, name it something like me named it State and selector will be same as for City field.
Now, click on the Add Post-Processing button to add the
RegexPost-Processing function, The below dialog box will appear.
Now, enter the Regular expression as
[^,]+,\s*(.*)in Expression parameter and enter the Group index as (
1) in Group parameter which shown in above screenshot.
Then, Save the function and the scraping agent configuration.
And finally, re-run you agent to apply the changes.
Now, if we notice the below screenshot, we get the new field State with updated result.
