Title: [SOLVED]Compile Error: WriteXMLFile(xml_doc, file_name)
Post by: kinlion on May 25, 2019, 06:52:33 am

Lazarsu2.0.2 + FPC3.0.4 On Win10x64

I met with a weird problem:

The compiler compains: Incompatible type for the arg no.2: Got "AnsiString", Expected "TStream"
at this code:

Code: Pascal  [Select][+][-]

1. WriteXMLFile(xml_doc, file_name);

However, if I use WriteXML instead, it has no problem.
I'm sure it's also no problem in Lazarsu1.8.4 + FPC3.0.4 On Win10x64 even using WriteXMLFile.

Is it a bug?

ReadXMLFile is similar

Sorry. I made a mistake.

The type of xml_doc should be TXMLDocument, but I defined it as a TDomDocument.

This one compiles without a problem:

Code: Pascal  [Select][+][-]

1. uses DOM, XMLWrite, XMLRead;
2.  
3. var
4.   S: string = '';
5.   Doc: TXMLDocument = nil;
6. begin
7.   WriteXMLFile(Doc, S);
8.   ReadXMLFile(Doc, S);
9. end.

Make a minimal project where the problem is reproduced.
