I have single-line and multi-line XML Summary texts, that look like these.
/// <summary> This is a single-line XML comment. </summary>
/// <summary> This is a multi-line XML comment.
/// These are additional lines with more text.
/// Some more of these text. </summary>
/// <summary> This is another XML text summary with a different
/// format.
/// </summary>
In RegexBuddy, how would I capture the texts within, without the /// and the <summary> </summary> tags?
I came up with the following to capture a multi-line XML summary:
((\s*(///)\s*((<summary>)?))(.*))+(</summary>)$
and a single XML summary:
\s*///\s*(<summary>).*(</summary>)$
But I've no idea how to capture just the text.
What would be the regular expression I would use, in order to capture just the text, so that I can use it in a replacement reference?
Thank you in advance.
Use the PCRE engine:
(?:^///\s*(?:<summary>)?|</summary>)(*SKIP)(*F)|(?:(?!</?summary>|^///(?!/)\s*).)+

Explanation
--------------------------------------------------------------------------------
(?: group, but do not capture:
--------------------------------------------------------------------------------
^ the beginning of the string
--------------------------------------------------------------------------------
/// '///'
--------------------------------------------------------------------------------
\s* whitespace (\n, \r, \t, \f, and " ") (0
or more times (matching the most amount
possible))
--------------------------------------------------------------------------------
(?: group, but do not capture (optional
(matching the most amount possible)):
--------------------------------------------------------------------------------
<summary> '<summary>'
--------------------------------------------------------------------------------
)? end of grouping
--------------------------------------------------------------------------------
| OR
--------------------------------------------------------------------------------
</summary> '</summary>'
--------------------------------------------------------------------------------
) end of grouping
--------------------------------------------------------------------------------
(*SKIP) 'SKIP' verb, skips the match
--------------------------------------------------------------------------------
(*F) 'FAIL' verb, triggers fail and backtracking
--------------------------------------------------------------------------------
| OR
--------------------------------------------------------------------------------
(?: group, but do not capture (1 or more times
(matching the most amount possible)):
--------------------------------------------------------------------------------
(?! look ahead to see if there is not:
