StringReplaceStringReplace is used for substituting substrings matching the given patterns. In[73]:=  |
Out[73]=
|
Named patterns can be used as strings on the right-hand side of the replacement rules. Note the use of RuleDelayed (⧴) to avoid premature evaluation. In[74]:=  |
Out[74]=
|
When using regular expressions, it is convenient to remember that "$0" on the right-hand side refers to the whole matched substring. In[75]:=  |
Out[75]=
|
You can limit the number of replacements made by specifying a third argument. In[76]:=  |
Out[76]=
|
Note that the replacement does not have to be a string. If the result is not a string, a StringExpression is returned. In[77]:=  |
Out[77]=
|
In[78]:=  |
Out[78]//InputForm=
|
There is limited support for using the old MetaCharacters option in conjunction with general string patterns, but this option is deprecated and its use should be avoided.
