Match header and values, mutliline using regex-CodePudding

I have a document with the following structure:

A header (some text without any whitespace in the same line)
A list (could be empty) of values:
Each value starts with a tab character, and then is text without any whitespaces.

I would like to build a regex pattern such that each match contains 1 header group and 0-n values group.

Here is what I am trying, which I believe it is quite close, but probably some small problem I can't find:

^(?P<header>[^\s] )$(?P<value>^\t[^\s]$)*

Thanks.

CodePudding user response：

You can repeat the second part starting with a newline and a tab.

Then repeat the inner part of the value group in its own non capture group to get the whole match in group value

^(?P<header>\S )(?P<value>(?:\n\t\S )*$)
