LPL: How to escape in string literal? Need to split on regex that includes

Question

Is anyone aware of how to escape less than and greater than chars in the string literals in LPL? I'm need include < and > in a regex to remove html tags from a rich text field, but the syntax doesn't seem to allow < and > in a regex that follows split on, e.g. split on "<[^>]*>". I think < and > are reserved chars to interpolate business class values, and I haven't found a way around this. I've tried escaping < and > with \ and also tried explicit Unicode characters. \u003C and \u003E. Thoughts? I'm open to other ways of removing HTML from rich text fields.

Thanks Michael! I ended up using the plain text operator, but that's also a nice solution. I may use it in the future.

This use case was inside a derived field, so I probably would have had to define a separate local field to use the regex; good note though 😁

The best way is the plain text operator you found. But, you can make your regular expression split work if you assign it to a local field and then split on that regular expression. For example: TestSplit is an Instance Action Parameters Input is RichText Parameter Rules Input required Local Fields RE is Alpha size 30 Buffer is Text Action Rules RE = "<[^>]*>" for each Input split on "" if (Buffer != "") Buffer += " " Buffer += each confirmation required "Message="

Still curious about escaping < and >, but found a plain text type operator that will likely resolve my issue.
