Hello @ecamerin
Have you tested Cell Splitter node; with ‘\’ as delimiter.

Cell Splitter

Hi @ecamerin ,
you can succeed only if the text you’re trying to extract always follows the same pattern, e.g. it’s in the third position, it’s after “Part X/”, it contains “Savings” etc… And the pattern must identify that text uniquely, that is with no ambiguity.
“Cell Splitter” - as suggested by @gonhaddock - would be the right solution in the first case

Hi @ecamerin and welcome to the Knime Community.

It’s not clear what you are trying to achieve.

I mean, if you want to extract some dynamic string that’s at a specific position, then you can use what has been suggested. If you need to extract “EnergySavings” from a string, then you just need to check if the string has it, and if it exists, then the extracted results will be… well “EnergySavings”…

To check if the string “EnergySavings” exists, you can use the IndexOf() instead of IndexOfChars(), like this:
indexOf($column1$, "EnergySavings")

When found, the IndexOf() will return the position where the string is.
If not found, IndexOf() will return -1:

You can then apply some rule to “extract” the “EnergySavings” text:
