I have this code which reads XML. I get a SIGSEGV error when reading
a NodeValue which has no content. For runtime it works ok because I
put in the try/except block, but this still produces error at design
time which is a nuisance. Any suggestions? Is there a way to check
for an empty node?
function GetNodeValue(AValueName: ShortString; var AValue:
ShortString): boolean;
begin
Result := false;
ANode := ADoc.DocumentElement.FindNode(AValueName);
if ANode <> nil then begin
try
AValue:= ANode.FirstChild.NodeValue;
Just a guess: check whether ANode.FirstChild<>nil before accessing
ANode.FirstChild.NodeValue.

That appears to work. No more AVs. Thanks!
