Another possibility – less likely but an outside one – is that there might be something about end of line terminators – ie windows uses CR LF, and linux/Unix uses LF. I only raise it because if you save to a file and load it seems OK, so there might be something getting the wrong line terminator (not your fault even).
(MacOS by contrast uses CR as a line terminator just to be convenient). Programs like ftp convert text files automatically in transmission, other communication protocols might not. Got bitten by it frequently when looking after cross platform software - moving text data and source to and from Unix from Windows files often need to be converted by utilities (I have one using sed). (Source would not compile until converted) John Bird From: Jolyon Smith Sent: Tuesday, December 03, 2013 10:50 AM To: NZ Borland Developers Group - Delphi List Subject: Re: [DUG] Strange Error in Android Could you post the first line of the XML so we can see what it comprises of ? i.e. what XML declaration does the string contain which the parser is rejecting ? As a result of the DOM Vendor implementation model in Delphi, behaviour on Windows is no indication of reliability on Android, iOS or OS X (as you are finding). For Android it seems that the key to your problem is in XML.Internal.AdomCore_4_3.pas, specifically the EvaluateXmlOrTextDecl() method of TXmlInputSource but without knowing what declaration is being presented to this method it's impossible to say whether the problem lies here, in the process of assigning the string from the HTTP response to the XML document or with the content of the XML string itself. There is potential for many slips twixt this particular cup and lip. Robert Martin Tue, 3 Dec 2013 09:03 Hi Jeremy Never done any Delphi Android work but is it possible it is a character set issue? I am only using XE2 nut if I look at XMLDoc.LoadFromXML() (I don't have a LoadXMLData) it takes an AnsiString on at UTF16 delphi string.

I am Sending an HTTP request to a server that is returning some XML in an Android app. However, I get an unexpected result. I am using Indy and the idHTTP.get() function which returns either a string or populates a stream. I started out first by loading the results into a string variable, i.e. buffer:=isHTTP.get() which returns the data fine, BUT if I call LoadXMLData(buffer) - (LoadXmlData() is in Xml.XMLDoc.pas) which is a function I have used a number of time in Delphi in normal Windows apps and never had a problem – that wasn’t something I did J However, if in the android app, I load the buffer variable into a string list then save that to file the call LoadXMLDocument() that takes a file name, it works fine !! Oh, the error I get is “ET_INVALID_XML_DECL line:-1” which indicates the XML is invalid but if I do a showmessage(buffer) its perfectly fine. I have tried loading the result into a stream and the reading it out into a string and I get the same error. I have tried removing the #13#10’s and STILL I get the error. If I write the XML to file first, no problem. I have tried using String and DOMStrings, but still the same error Anyone got any ideas? I shouldn’t have to write the xml to file then load it, that’s a bit of a pain.
