Unable to isolate segments of a string

Unable to isolate segments of a string

Looking for a way to extract two different IDs from the following string:

SPList:6E5F5E0D-0CA4-426C-A523-134BA33369D7?SPWeb:C5DD2ADA-E0C4-4971-961F-233789297FE9:

using Javascript.

The regular expression being used is :

^SPList\:(?:[0-9A-Za-z\-]+)\?SPWeb\:(?:[0-9A-Za-z\-]+)\:$

, which should ideally result in two matching groups containing the extracted IDs.

Despite attempts, the current code fails to properly extract the IDs as expected. The first match includes the entire string while the second match appears as undefined.

If you have insights on a more effective method to extract these IDs, please share your thoughts.

For further reference, there is a jsfiddle demonstrating the issue at hand.

Answer №1

Your solution is perfect for what you need:

const pattern = /^SPList:([0-9A-F-]+)[?]SPWeb:([0-9A-F-]+):$/g;
const result = pattern.exec(input);
const listId = result[1];
const webId = result[2];

I made a slight adjustment to your original regex by turning non-capturing groups into capturing groups, and I used pattern.exec(input) instead of input.match(pattern) to extract the specific data we're looking for. Additionally, since the IDs appear to be in hexadecimal format, I changed the range from A-Z to A-F.

Give this a shot:

        let regexPattern = /[^\:]([0-9A-Z\-]+)[^\?|\:]/g;
        let matches = userInput.match(regexPattern);
        console.log("listID: " + matches[1] + "\n" + "webID: " + matches[3]);
