| Dear All,
|
| I have a list of strings representing numbers, i.e. a =
| {"12223","11313","2424"} that I generated in XML and read into
| mathematica. How do I convert this into a list of integers?

| Yours Ever and Merry Christmas,

Hi Chrisantha,

You can use the built-in function *ToExpression* (see In[4]):

In[1]:= lst = {"12223", "11313", "2424"}
Out[1]= {12223,11313,2424}

In[2]:= FullForm[lst]
Out[2]//FullForm= List["12223","11313","2424"]

Out[3]= {String,String,String}

In[4]:= data = ToExpression[lst]
Out[4]= {12223,11313,2424}

In[5]:= FullForm[data]
Out[5]//FullForm= List[12223,11313,2424]
