vb.net: can you split a string by a string

for example, can i do this:

split = temp_string.Split("<beginning of record>")

those of you recommended:

split = Regex.Split(temp_string, "< beginning of record >")

its not working. its just returning the first char "<"

and those of you that recommended:

Dim myDelims As String() = New String(){"< beginning of record >"}
split = temp_string.Split(myDelims, StringSplitOptions.None)

this is not working either. it's also returning just the first char
