How to split string by multiple pairs of delimiters - powerbi

Question

Is there a way to split string by delimiters if delimiters are pairs enclosing required text?
E.g. If source string is:
[Text1] [Text2] [Text3] ...
I want to have result as
Text1
Text2
Text3
Function Text.BetweenDelimiters picks up only first pair of [].
I guess I need somehow to create a loop. In e.g. Python it is a few lines of code. I cannot figure out how to do it in M.
If something like that s possible do in DAX, that would go too.

You can do it like this:
replace "] [" with ";"
remove "[" and "]"
split by ";"
unpivot columns
let
Source = Table.FromList(
{
"[Text1] [Text2] [Text3]",
"[Text4] [Text5] [Text6]"
},
null, {"Text"}
),
#"Replaced Value" = Table.ReplaceValue(
Source,"] [",";",Replacer.ReplaceText,{"Text"}),
#"Replaced Value1" = Table.ReplaceValue(
#"Replaced Value","[","",Replacer.ReplaceText,{"Text"}),
#"Replaced Value2" = Table.ReplaceValue(
#"Replaced Value1","]","",Replacer.ReplaceText,{"Text"}),
#"Split Column by Delimiter" = Table.SplitColumn(
#"Replaced Value2", "Text",
Splitter.SplitTextByDelimiter(";", QuoteStyle.Csv),
{"Text.1", "Text.2", "Text.3"}
),
#"Changed Type" = Table.TransformColumnTypes(
#"Split Column by Delimiter",
{
{"Text.1", type text},
{"Text.2", type text},
{"Text.3", type text}
}
),
#"Unpivoted Columns" = Table.UnpivotOtherColumns(
#"Changed Type", {}, "Attribute", "Value"),
#"Removed Columns" = Table.RemoveColumns(
#"Unpivoted Columns",{"Attribute"})
in
#"Removed Columns"
The way you put your "sample data" you can even omit step 1 and split by " ".

One way .. split on ] [ then replace the two odd-men odd:
right click .. split column .. by delimeter. Use ] [ and split into rows
right click and replace [ with nothing
right click and replace ] with nothing
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Split Column by Delimiter" = Table.ExpandListColumn(Table.TransformColumns(Source, {{"Column1", Splitter.SplitTextByDelimiter("] [", QuoteStyle.Csv), let itemType = (type nullable text) meta [Serialized.Text = true] in type {itemType}}}), "Column1"),
#"Replaced Value" = Table.ReplaceValue(#"Split Column by Delimiter","[","",Replacer.ReplaceText,{"Column1"}),
#"Replaced Value1" = Table.ReplaceValue(#"Replaced Value","]","",Replacer.ReplaceText,{"Column1"})
in #"Replaced Value1"
