Hi everyone,

I'm new to Delphi and I was given a project written on Delphi 7 under Windows XP operating system.

I opened the project in Delphi 9, the upgrade was done successfully but returned the following error:

[DCC Error] qrxdocument.pas(57): E2003 Undeclared identifier: 'TDomDocument'.

When hovering the mouse in the code, it lets me know that TDomDocument does exist in MSXML_TLB.pas but nevertheless, gives an error.

Could anyone help me? I would really appreciate your help.
