[fpc-devel] XML Stream capacity
I'm using fcl-xml to parse a XML data from a TMemoryStream/TStringStream and noted it can parse streams with a maximum capacity of 4096 bytes, why can't it receive bigger streams?. The maximum capacity is defined in the constructor of TXMLStreamInputSource, in XMLRead.pp. --- constructor TXMLStreamInputSource.Create(AStream: TStream; AOwnStream: Boolean); begin FStream := AStream; FCapacity := 4096; -- here's the max capacity allowed ... --- My testing code is this: var lDoc: TXMLDocument; lStr: TStringStream; begin lStr := TStringStream.Create(Memo1.Text); lDoc := TXMLDocument.Create; try ReadXMLFile(lDoc, lStr); finally lDoc.Free; lStr.Free; end; end.

The maximum capacity is defined in the constructor of TXMLStreamInputSource, in XMLRead.pp. This value has nothing to do with total possible stream size, it is only the size of buffer used while reading. The maximum size of XML data that can be read with DOM on a 32-bit machine is about 40 to 150 MBytes (depending on the data structure).

Re: [fpc-devel] XML Stream capacity
Thanks Sergey. I tought that was why my program was stopping with an assertion in procedure TNodePool.AddExtent of dom.pp, the assertion dissapears when I work with smaller XML files. BTW: the file worked with older versions of fcl-xml, now I'm using the trunk version because it no longer deppends on AVL_Tree, that wasn'n thread safe. I attached the file I'm using for testing.
