Parse $Text for hashtags and populate $Tags

If you had this in $Text and wanted to parse it so all the hashtags out of the text, leaving the text untouched, and put the hashtags as a semicolon-separated set in $Tags how would you go about it?

I’ve tried various .following stamps (don’t want to use replace because I want to keep the text untouched.

This might be a start but you need to create $MyList2 first:

$MyList=$Text.split(" β€œ);
$MyList.each(x){
if(x.contains(”#")){
$MyList2=$MyList2+x+";";}
};

Result: #impact;#insight;laborum.
#personaldata;#identity;#marketassessment;#selfsovereignidentity;#ssi;#authenticdata;#verifiablecredentials;#personaldatastores;#personalinformationmanagementsystems

Unfortunately, that did not work for me. Also, I want the # to be removed. The .split is a nice idea. I’ll explore that.

Slightly easier:

$MyList=$Text.split(" ");
$MySet=$MyList.collect_if(x,  x.beginsWith("#"), x.substr(1) );

$Text.wordList() would be better than using split(), but it strips out the β€œ#”.

I think this might be a good topic to explore in the meetup.

It might also be a good candidate for a simpler action, like the `.extract()`` operator we discussed a few days back. In a way, this is the same problem, except that here you do want to capture all matches, not just the first.
