How to use Xerces Library to parse the XML file with Visual C++ Project

The Apache project's Xerces-C libraries support the DOM approach to XML parsing. The entire XML file is imported into memory and the data is held as nodes in a data tree which can be traversed for information.

The Xerces-C C++ parser home page: http://xml.apache.org/xerces-c/

So download the latest version of  Xerces Library and place it into your project  folder.

The Xerces Library folder contains the following files and folders inside it Shown in the picture .

Now make a new project or open your current project and Right click your project and go to “project properties”. Now go to “VC++ directories” and then go to “Include directories” and give the path of the Xerces Library include folder as shown in the picture below.

Now go to “VC++ directories” and then go to “Library directories” and give the path of the Xerces Library lib folder as shown in the picture below.

Now go to “Linker” -> “Input” and then go to “Additional directories” and give the path of the Xerces Library file as shown in the picture below.

Now write the following code to parse the directories.

#include <iostream>

#include <xercesc/dom/DOM.hpp>

#include <xercesc/dom/DOMElement.hpp>

#include <xercesc/dom/DOMNode.hpp>

#include <xercesc/dom/DOMText.hpp>

#include <xercesc/parsers/XercesDOMParser.hpp>

#include <xercesc/sax/HandlerBase.hpp>

using namespace std;

using namespace xercesc;

void write(DOMNode* node);

void writeElement(DOMElement* element);

void writeText(DOMText* text);

void

write(DOMNode* node) {

     if (node) {

           switch (node->getNodeType()) {

           case DOMNode::ELEMENT_NODE:

                writeElement(static_cast<DOMElement*>(node));

                break;

           case DOMNode::TEXT_NODE:

                writeText(static_cast<DOMText*>(node));

                break;

           }

           DOMNode* child = node->getFirstChild();

           while (child) {

                DOMNode* next = child->getNextSibling();

                write(child);

                child = next;

           }

     }

}

void

writeElement(DOMElement* element) {

     char* name = XMLString::transcode(element->getTagName());

     cout << "tag    : " << name << endl;

     XMLString::release(&name);

     DOMNamedNodeMap* map = element->getAttributes();

     for (XMLSize_t i = 0; i < map->getLength(); i++) {

           DOMAttr* attr = static_cast<DOMAttr*>(map->item(i));

           char* attr_name  = XMLString::transcode(attr->getName());

           char* attr_value = XMLString::transcode(attr->getValue());

           cout << attr_name << ": "<< attr_value << endl;

           XMLString::release(&attr_name);

           XMLString::release(&attr_value);

     }

}

void

writeText(DOMText* text) {

     XMLCh* buffer = new XMLCh[XMLString::stringLen(text->getData()) + 1];

     XMLString::copyString(buffer, text->getData());

     XMLString::trim(buffer);

     char* content=XMLString::transcode(buffer);

     delete[] buffer;

     cout << "content: " << content << endl;

     XMLString::release(&content);

}

int main(int argc, char* args[]) {

     try {

           XMLPlatformUtils::Initialize();

     } catch (const XMLException& toCatch) {

           char* message = XMLString::transcode(toCatch.getMessage());

           cout << "Error during initialization! :\n" << message << "\n";

           XMLString::release(&message);

           return 1;

     }

     XercesDOMParser* parser = new XercesDOMParser();

     parser->setValidationScheme(XercesDOMParser::Val_Always);

     parser->setDoNamespaces(true); // optional

     ErrorHandler* errHandler = (ErrorHandler*) new HandlerBase();

     parser->setErrorHandler(errHandler);

     const char* xmlFile = "samples/data/personal.xml";

     try {

           parser->parse(xmlFile);

           DOMDocument* dom = parser->getDocument();

           write(dom);

     } catch (const XMLException& toCatch) {

           char* message = XMLString::transcode(toCatch.getMessage());

           cout << "Exception message is: \n" << message << "\n";

           XMLString::release(&message);

           return -1;

     } catch (const DOMException& toCatch) {

           char* message = XMLString::transcode(toCatch.msg);

           cout << "Exception message is: \n" << message << "\n";

           XMLString::release(&message);

           return -1;

     } catch (...) {

           cout << "Unexpected Exception \n";

           return -1;

     }

     delete parser;

     delete errHandler;

     return 0;

}

Compile:

• RPM installed: g++ -g -Wall -pedantic -lxerces-c parser.cpp -DMAIN_TEST -o parser 

or

• Installed to "/opt": g++ -g -Wall -pedantic -I/opt/include -L/opt/lib -lxerces-c parser.cpp -DMAIN_TEST -o parser

Now Run  the program..
