Remove Text Between - Power BI
I am working on removing some text with pattern below "[cig ...]"; "[http ...]"; "[data ...]"; by creating 3 fucntions. Attached 1 at the bottom as reference. However, when I apply the function, some of the cell get the error (An error occurred in the ‘’ query. Expression.Error: The 'count' argument is out of range. Details: -2360)
May I know how can I solve this error?
Remark:
Code of the fucntion learnt from another export: https://stackoverflow.com/questions/60640977/power-query-remove-text-between-delimiters
Error Message:
Function:
= (txt as text) =>
[
fnRemoveFirstTag = (HTML as text)=>
let
OpeningTag = Text.PositionOf(HTML,"[cid"),
ClosingTag = Text.PositionOf(HTML,"]"),
Output =
if OpeningTag = -1
then HTML
else Text.RemoveRange(HTML,OpeningTag,ClosingTag-OpeningTag+1)
in
Output,
fnRemoveHTMLTags = (y as text)=>
if fnRemoveFirstTag(y) = y
then y
else @fnRemoveHTMLTags(fnRemoveFirstTag(y)),
Output = @fnRemoveHTMLTags(txt)

Hi kenchan
Please provide your file or at least sample data to run this code against. Hard to debug it without the data it's using.

Thank you for your response; I attached the link for the data.
Step to get the error:
I would like to remove the the strings( "[cid ...]"; "[http ...]"; "[data ...]") in each cells of the file. I simply import the file into power bi; copy and paste the function below and create a new col and apply the function. However, I encounter the error "The 'count' argument is out of range". Thank you for your help and support.
the function for removing [cid ...]
Function:
= (txt as text) =>
[
fnRemoveFirstTag = (HTML as text)=>
let
OpeningTag = Text.PositionOf(HTML,"[cid"),
ClosingTag = Text.PositionOf(HTML,"]"),
Output =
if OpeningTag = -1
then HTML
else Text.RemoveRange(HTML,OpeningTag,ClosingTag-OpeningTag+1)
in
Output,
fnRemoveHTMLTags = (y as text)=>
if fnRemoveFirstTag(y) = y
then y
else @fnRemoveHTMLTags(fnRemoveFirstTag(y)),
Output = @fnRemoveHTMLTags(txt)

There's probably some limit, like 32,7xx characters.
But couldn't you use those tags as the delimiter, use Text.BetweenDelimiters to get your substrings, and then use those each of those substrings as a parameter to Text.Replace, and replacing with nothing?
Im not at my desk, but you seem to understand functions. Hopefully this gets you started, I'll be in later to check back.

Thank you for your insight. I try; I believe it solved part of my question. However, if the cell have happen the pattern twice, it may not able to handle at once time. Is there any fucntion which I can handle this?
