API Delete numbered note based on found text?

I'm trying to delete a note based on whether the bulleted note has text such as ROHS in it.
I'm using "PropertyLinkedText Property (INote)" to get a fully formatted note. 
But I'm not sure how to isolate selecting the single line to delete out of the note. 

In some cases, the example "ROHS" could be mentioned in multiple parts of the notes and I want to remove all lines that reference it. 

For example, I want to delete line 9. a. out of this note:


Does anyone know of an easy way to do this?

Is there a way to find a carriage return within a note?
The formatted text that iNote returns doesn't look to have a character for carriage return, but something obviously tells the line to return. 
Here is a sample of the formatted text that is returned for the above sample.
