Regex: Capture Groups and Empty Fields (SWIFT 5 | ICU Regex Engine) - swift

Question

I am in need of some help correcting my RegEx string - I have a string of text (A large body of HTML) and I need to take this HTML String and then pattern match it so that data that I have nested within' <div> tags can be extracted and used.
Lets take an example with a test case of <div id=1>
<div id=1>UID:1currentPartNumber:63222TRES003H1workcenter:VLCSKDcycleTime:98.8curPartCycleTime:63.66partsMade:233curCycleTimeActual:62.4target:291actual:233downtime:97statusReason:lineStatus:Productionefficiency:80.05plusminus:-260curProdTime:7/16/2019 12:28:01 PM</div>
What should be noted is that lineStatus can either have a value or be empty such as the same with statusReason
I am able to come up with a regex that does MOST of the work but I am struggling with cases where values are not present.
Here is my attempt:
(
(<div id=(\d|\d\d)>)
(UID:(\d|\d\d))
(currentPartNumber:(.{1,20}))
(workcenter:(.{1,20}))
(cycleTime:(.{1,6}))
(curPartCycleTime:(.{1,6}))
(partsMade:(.{1,6}))
(CycleTimeActual:(.{1,6}))
(target:(.{1,6}))
(actual:(.{1,6}))
(downtime:(.{1,6}))
((statusReason:((?:.)|(.{1,6}))))
((lineStatus:((?:.)|(.{1,6}))))
(Productionefficiency:(.{1,6}))
(plusminus:(.{1,6}))
(curProdTime:(.{1,30}))
)
Split it up just for readability.
Thanks,

You are very, very close.
If you use:
(
(<div id=\d{1,2}>)
(UID:\d{1,2})
(currentPartNumber:(.{1,20}))
(workcenter:(.{1,20}))
(cycleTime:(.{1,6}))
(curPartCycleTime:(.{1,6}))
(partsMade:(.{1,6}))
(CycleTimeActual:(.{1,6}))
(target:(.{1,6}))
(actual:(.{1,6}))
(downtime:(.{1,6}))
(statusReason:(.{0,6}))
(lineStatus:(.{0,6}))
(Productionefficiency:(.{1,6}))
(plusminus:(.{1,6}))
(curProdTime:(.{1,30}))
(<\/div>)
)
Then $3\n$4\n$6\n$8\n$10\n$12\n$14\n$16\n$18\n$20\n$22\n$24\n$26\n$28\n$30 will be:
UID:1
currentPartNumber:63222TRES003H1
workcenter:VLCSKD
cycleTime:98.8
curPartCycleTime:63.66
partsMade:233cur
CycleTimeActual:62.4
target:291
actual:233
downtime:97
statusReason:
lineStatus:
Productionefficiency:80.05
plusminus:-260
curProdTime:7/16/2019 12:28:01 PM
By using (statusReason:(.{0,6}))(lineStatus:(.{0,6})) you make the value of statusReason and lineStatus truly optional.
I also simplified the start <div> and UID detection.

Try Regex: ((<div id=(\d|\d\d)>)(UID:(\d|\d\d))(currentPartNumber:(.{1,20}))(workcenter:(.{1,20}))(cycleTime:(.{1,6}))(curPartCycleTime:(.{1,6}))(partsMade:(.{1,6}))(CycleTimeActual:(.{1,6}))(target:(.{1,6}))(actual:(.{1,6}))(downtime:(.{1,6}))(statusReason:(.{1,6})?)(lineStatus:(.{1,6})?)(Productionefficiency:(.{1,6}))(plusminus:(.{1,6}))(curProdTime:(.{1,30})))
