(HTTPSocket httpGet: aUrl) contents I know we Smalltalkers like to talk about how no one ever gets confused about dynamic types, but it does happen ;-).
The stream has the text you want. May want to familiarize yourself with core methods on the Stream hierarchy. Pushing the Stream through a ByteArray conversion is invoking printString. Your trouble with getting a modified string using replaceAll: is again a subtle typing error: Reading the comment for #replaceAll:with: "Replace all occurences of oldObject with newObject" But, Strings are collections of characters, not strings. Compare: 'foo' replaceAll: 'f' with: 'g' 'foo' replaceAll: $f with: $g Take a look at senders of #findString: Many of them do replacements of substrings.
