Basic Examples

In[]:=
Split a string after each whitespace:
[◼]
StringSplitAfter
["a bbb cccc aa d"]
In[]:=
{a ,bbb ,cccc ,aa ,d}
Out[]=
Split a string after every --:
[◼]
StringSplitAfter
["a--bbb---ccc--dddd","--"]
In[]:=
{a--,bbb--,-ccc--,dddd}
Out[]=

Scope

In[]:=
Split after every run of spaces:
[◼]
StringSplitAfter
["the cat in the hat"]
In[]:=
{the ,cat ,in ,the ,hat}
Out[]=
Use string patterns:
[◼]
StringSplitAfter
["192.168.0.1","."]
In[]:=
{192.,168.,0.,1}
Out[]=
[◼]
StringSplitAfter
["123 2.3 4 6",WhitespaceCharacter..]
In[]:=
{123 ,2.3 ,4 ,6}
Out[]=
[◼]
StringSplitAfter
["11a22b3",_?LetterQ]
In[]:=
{11a,22b,3}
Out[]=
Regular expressions:
[◼]
StringSplitAfter
["A tree, an apple, four pears. And more: two sacks",RegularExpression["\\W+"]]
In[]:=
{A ,tree, ,an ,apple, ,four ,pears. ,And ,more: ,two ,sacks}
Out[]=
Mixed regular expressions and string patterns:
[◼]
StringSplitAfter
["primes: 2 two 3 three 5 five ...",Whitespace~~RegularExpression["\\d"]~~Whitespace]
In[]:=
{primes: 2 ,two 3 ,three 5 ,five ...}
Out[]=
Split into substrings after either delimiter:
[◼]
StringSplitAfter
["a-b:c-d:e-f-g",{":","-"}]
In[]:=
{a-,b:,c-,d:,e-,f-,g}
Out[]=
[◼]
StringSplitAfter
["a-b:c-d:e-f-g",":"|"-"]
In[]:=
{a-,b:,c-,d:,e-,f-,g}
Out[]=
Replace a delimiter:
[◼]
StringSplitAfter
["a b::c d::e f g","::""--"]
In[]:=
{a b--,c d--,e f g}
Out[]=
SplitStringAfter
automatically threads over lists of strings:
[◼]
StringSplitAfter
[{"a:b:c:d","listable:element"},":"]
In[]:=
{{a:,b:,c:,d},{listable:,element}}
Out[]=

Options

In[]:=
Split a string after every "c", including uppercase letters:
[◼]
StringSplitAfter
["cat Cat hat CAT","c",IgnoreCaseTrue]
In[]:=
{c,at C,at hat C,AT}
Out[]=
