TYPO3 - get last element of a splitted string - typo3

Question

Trying to get the last part of the url as a body class. So far I got the slug of the page and split it by /
page.bodyTag >
page.bodyTagCObject = TEXT
page.bodyTagCObject.field = slug
page.bodyTagCObject.split {
token = /
cObjNum = 1
1.10 = TEXT
1.10.current = 1
1.10.noTrimWrap = | ||
1.10.dataWrap = |
1.10.required = 1
}
With this code, I am getting:
url: page/foo/bar/
class="page foo bar"
I need to get class="bar"

You'll need to use optionSplit for that. For example:
lib.test = TEXT
lib.test {
value = 1,2,3,4
split {
token = ,
cObjNum = 1 |*| 2 |*| 3
1 = TEXT
1 {
current = 1
wrap = First item:|<br/>
}
2 = TEXT
2 {
current = 1
wrap = Middle item:|<br/>
}
3 = TEXT
3 {
current = 1
wrap = Last item:|<br/>
}
}
}
1 |*| 2 |*| 3 means: use 1 for the first item, 3 for the last item and 2 for the rest.
You can just not set the ones you don't want, so this will only show the last item:
cObjNum = 1 |*| 1 |*| 2
2 = TEXT
2 {
current = 1
wrap = Last item:|<br/>
}
