I want to parse simple XML file using xerces, for that I download ‘xerces-c-3.1.4’. From their sample code I did the DomPrint program in visual studio 2013.
here is my code:
#include <xercesc/util/PlatformUtils.hpp>

#include "D:\xecerces_download\xerces-c-3.1.4\src\xercesc\util\PlatformUtils.hpp"

#include"D:\xecerces_download\xerces-c-3.1.4\src\xercesc\framework\LocalFileFormatTarget.cpp"
#include <xercesc/dom/DOM.hpp>
#include <xercesc/framework/StdOutFormatTarget.hpp>
#include <xercesc/framework/LocalFileFormatTarget.hpp>
#include <xercesc/parsers/XercesDOMParser.hpp>
#include <xercesc/util/XMLUni.hpp>
#include "DOMTreeErrorReporter.hpp"
#include "DOMPrintFilter.hpp"
#include "DOMPrintErrorHandler.hpp"
#include <xercesc/util/OutOfMemoryException.hpp>

Usage:
"
" DOMPrint [options] <XML file>
"
"This program invokes the DOM parser, and builds the DOM tree.
"
"It then asks the DOMLSSerializer to serialize the DOM tree.
"
"Options:
"
" -e create entity reference nodes. Default is no expansion.
"
" -v=xxx Validation scheme [always | never | auto*].
"
" -n Enable namespace processing. Default is off.
"
" -s Enable schema processing. Default is off.
"
" -f Enable full schema constraint checking. Defaults is off.
"
" -wenc=XXX Use a particular encoding for output. Default is
"
" the same encoding as the input XML file. UTF-8 if
"
" input XML file has not XML declaration.
"
" -wfile=xxx Write to a file instead of stdout.
"
" -wscs=xxx Enable/Disable split-cdata-sections. Default on
"
" -wddc=xxx Enable/Disable discard-default-content. Default on
"
" -wflt=xxx Enable/Disable filtering. Default off
"
" -wfpp=xxx Enable/Disable format-pretty-print. Default off
"
" -wbom=xxx Enable/Disable write Byte-Order-Mark Default off
"
" -xpath=xxx Prints only the nodes matching the given XPath.
"
" -? Show this help.
"
" * = Default if not provided explicitly.
"
"The parser has intrinsic support for the following encodings:
"
" UTF-8, US-ASCII, ISO8859-1, UTF-16[BL]E, UCS-4[BL]E,
"
" WINDOWS-1252, IBM1140, IBM037, IBM1047.

which showing errors: 1. Cannot open include file: ‘xercesc/util/PlatformUtils.hpp’: No such file or directory
2. IntelliSense: ‘operator=’ must be a member function
3. IntelliSense: cannot open source file “xercesc/util/PanicHandler.hpp”
4. IntelliSense: cannot open source file “xercesc/util/XercesDefs.hpp” and many more.
for that 1.I added respective .hpp file 2. set precompiled header–>no 3. set path " D:\xecerces_download\xerces-c-3.1.4\src\xercesc" in project–>property–>c/c+±->general 4. project–>property–>linker–>input–>xerces-c_3D.lib;%(AdditionalDependencies)
still so many errors are there,Can you please help me to sort it out?
