I have a text line and I need capture the value "Keyword" key.
In this sample the value is "ConquestImageDate".
With my code below I can capture the value as ConquestImageDate".
But it has a '"' on the end.
I know I can use a replace to get rid off it.
But, I´d like to do it in the regex.
let line =
'(0008,0023) VERS="CQ" VR="DA" VM="1" Keyword="ConquestImageDate" Name="Conquest Image Date"';
const re = /Keyword=\"\s*(\S+)/;
m = re.exec(line);
console.log(m[1]);
You are not matching the closing ", and as exec might yield null you can check for m first before indexing into it.
let line =
'(0008,0023) VERS="CQ" VR="DA" VM="1" Keyword="ConquestImageDate" Name="Conquest Image Date"';
const re = /Keyword="\s*(\S+)"/;
m = re.exec(line);
if (m) {
console.log(m[1]);
}If there can also be unwanted whitespace chars at the end, you could making the \S non greedy.
let line =
'(0008,0023) VERS="CQ" VR="DA" VM="1" Keyword="ConquestImageDate" Name="Conquest Image Date"';
const re = /Keyword="\s*(\S*?)\s*"/;
m = re.exec(line);
if (m) {
console.log(m[1]);
}You are matching Keyword which is singular, but if in any case you want to match spaces or newlines as well between the double quotes
\bKeyword="\s*([^"]*?)"
