<br>
looks like this:<br>
<br>
| data |<br>
data := String<br>
fromByteArray: (HTTPSocket httpGet: anUrl).<br>
<br>
i end up with a string that has my desired data (a JSON string), but,<br>
it's preceeded by this:<br>
<br>
'a RWBinaryOrTextStream ' '<here is the stuff i need>' ' '<br>
<br>
i am trying to lop off the first part by doing:<br>
<br>
jsonData := dataString replaceAll: 'RWBinaryOrTextStream' with: 'test'.<br>
<br>
just to see if i can touch the string..<br>
<br>
but no matter what i do, i can't get any parts of the string to be raplaced..<br>
<br>
it almost looks like there are three strings in there..<br>
<br>
the RWBinaryOrTextStream one, the one i need, and an empty one..<br>
<br>
is there a better way to pull a url?<br>
<br>
thanks!<br>
<br>
