如何以编程方式更改图像文件路径？

Question

This is an example of image location I need to change:

<img src="file:///Users/User/Library/Developer/CoreSimulator/Devices/B343D95A-92FD-42E4-B10E-BF85210FBC33/data/Containers/Data/Application/662DCB20-3D51-467C-9968-8CA463304B46/Documents/data/a1a1a1/xyz.gif"

This is what I want to remove and put something else there: data/a1a1a1/

With the function below I have successfully removed this part: data/ and put what I wanted there. Works fine because folder name data never changes.
Problem I want to remove this part now : a1a1a1/ but problem is that a1a1a1 can be anything, for example it can be aef54e3a ...
Does anyone have an idea how to remove that part of the html string?

Function :

 func findSrcs(_ content: String) -> String {
        let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
        let documentsDirectory = paths[0]

        let pattern = #"(?<=src=")[^"]+"#

        var x = content //content is a highlighted string I put above
        var startIndex = content.startIndex
        while let range = content[startIndex...].range(of: pattern, options: .regularExpression) {

                startIndex = range.upperBound
                let c = content.replacingOccurrences(of: "data/", with: "\(documentsDirectory)", options: .literal, range: nil)
                //let d = c.replacingOccurrences(of: "7216444/", with: "", options: .literal, range: nil)
          x = c
        }
        return x
    }

You can change the code inside the while loop to this:

let url = URL(fileURLWithPath: String(content[range]))
x = documentsDirectory.appendingPathComponent(url.lastPathComponent)

Though I'm not sure if you want just a single x returned (and then why use while ?) or an array of of paths (and then the function should return [String] ).
