<DIV>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).</DIV>
<DIV> </DIV>
<DIV>(MacOS by contrast uses CR as a line terminator just to be
convenient).</DIV>
<DIV> </DIV>
<DIV>Programs like ftp convert text files automatically in transmission, other
communication protocols might not.</DIV>
<DIV> </DIV>
<DIV>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)</DIV>

you post the first line of the XML so we can see what it comprises of ?

finding).<BR><BR>For Android it seems that the key to your problem is in
XML.Internal.AdomCore_4_3.pas, specifically the EvaluateXmlOrTextDecl() method

of assigning the string from the HTTP response to the XML document or with the

<P class=MsoNormal>Hi All.<o:p></o:p></P>
<P class=MsoNormal>I am Sending an HTTP request to a server that is returning
some XML in an Android app.<o:p></o:p></P>
<P class=MsoNormal>However, I get an unexpected result. I am using Indy and
the idHTTP.get() function which returns either a string or populates a
stream.<o:p></o:p></P>
<P class=MsoNormal>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 <SPAN
style="FONT-FAMILY: wingdings">J</SPAN><o:p></o:p></P>
<P class=MsoNormal>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 !!<o:p></o:p></P>
<P class=MsoNormal>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.<o:p></o:p></P>
<P class=MsoNormal>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.<o:p></o:p></P>
<P class=MsoNormal>I have tried using String and DOMStrings, but still the
same error<o:p></o:p></P>
<P class=MsoNormal><o:p></o:p> </P>
<P class=MsoNormal>Anyone got any ideas? I shouldn’t have to write the xml to
file then load it, that’s a bit of a pain.<o:p></o:p></P>
<P class=MsoNormal><o:p></o:p> </P>
<P class=MsoNormal><o:p></o:p> </P>
<P class=MsoNormal>Thanks, Jeremy<o:p></o:p></P>
