Prettyprint & newline ?‏‏

I am a beginner and started to use xerces-c-src_2_8_0 with C++ in VisualStudio 2005
I have the following code which is supposed to read Test1.txt then dump it to Test2.txt
Content of Test1.txt is listed under the code.
The problem is, when I open output file "Test2.txt" using "notepad" I see all lines combined such as
<?xml version="1.0" encoding="UTF-8" standalone="no" ?> [] [] <Items> [] <Item a="1"> []  </Item> [] </Items> [] []

Am I doing somthing wrong? I wish to be able to split these into several lines

Thanks for your help

This is a memory leak.  You need to free the pointer return by the
transcode function:

    XMLCh* lfSeq = XMLString::transcode("\r\n");
    theSerialize->setNewLine(lfSeq);
    XMLString::release(&lfSeq);

Also, the DOS sequence is CR/LF, so you want "\r\n" instead of "\n\r".

Thanks Dave for your answer. That seemed to help splitting the header "<?xml version="1.0"....." and body "<Items ..." into two separate lines. However, the body is still a one-line printout.
Is there an easy way to be able to split the body further to look more like a tree, preferably with appropriate tab indent?
My alternative is to iterate through the DOM tree and output the file myself, but I am hoping that there is a magical command in xerces that I am not aware of to do that.

You're still setting XMLUni::fgDOMWRTFormatPrettyPrint, right?  If so, the output should be pretty-printed.  (Note that "pretty" is a matter of taste.  I modify the implementation in xercesc\DOM\Impl\DOMWriterImpl.cpp to emit fewer line breaks and less indenting in some cases.)

If you're setting the flag and it's not getting pretty-printed, it may be time for a session with a debugger to figure out why.
