HTTP Response exceeds the size of the string buffer

Dave_Cintron · 2011-07-22

I am trying to receive an XML document through HTTP but when it exceeds 1024 it errors out.

I have tried to use the Node object, but to get to the node you have to load the XML Doc, and to load the XML Doc, you have to receive the HTTP response, and you get the error.

The XMLHTTP responsetext will not INSTREAM and even ADDTEXT throws the error.

It seems this 1024 limit applies to any operation. What to do?

Finally worked it out like this:

XMLDoc.load(XMLHttp.responseStream);
XMLNodeList := XMLDoc.childNodes;
FOR NodeNo := 0 TO XMLNodeList.length-1 DO BEGIN
  XMLNode := XMLNodeList.item(NodeNo);
  NodeName := XMLNode.nodeName;
  IF XMLNode.hasChildNodes THEN BEGIN
    XMLNodeList2 := XMLNode.childNodes;

.. iterate through child nodes

Howdy, Stranger!
