XMLManager class - wraps essential XML functions allowing easy access and managment of XML data.

Introduction

This wrapper class - wraps around functions for XML access, storage and retrieval of data. It allows easy access and manipulation of data stored as an XML file. The usage is very easy and is perfect for any serialization needs especially of a tree based data.

Usage

First include the XMLManager.h and XMLManager.cpp files in your project.

Create an instance of the class:

CXMLManager xmlManager;

Don't forget to include the XML support in your project:

 #import "msxml.dll" named_guids raw_interfaces_only

Usually in your stdafx.h.

Create an XML document pointer:

HRESULT hr = S_OK;
 MSXML::IXMLDOMDocument *pDoc = NULL;

 CoInitialize(NULL);

 CHECKHR(CoCreateInstance(MSXML::CLSID_DOMDocument, NULL, 
                                CLSCTX_INPROC_SERVER,
                                MSXML::IID_IXMLDOMDocument, 
                                (void**)&pDoc));

Now use the XMLManager in the folowing way:

Serialization:

// Load the XML file
HRESULT CXMLManager::LoadDocument(
    MSXML::IXMLDOMDocument *pDoc,    // Pointer to XML Document you created

    char* fileName            // The file name (C:\mydata.xml)

);
// Save the document to a file



HRESULT CXMLManager::SaveDocument(
    MSXML::IXMLDOMDocument *pDoc,     // Pointer to XML Document
    char* fileName             // Desired filename (rewrite if exists)
);

Data retrieval:

// Get child node of any parent node
MSXML::IXMLDOMNode* CXMLManager::GetChild(
    MSXML::IXMLDOMNode *pNode,    // The parent node 
    CString name            // The name of the desired child
);
// Retrieve the name of XML node
CString CXMLManager::GetNodeName(
    MSXML::IXMLDOMNode *pNode    // The node who's name is required
);
// Three functions to get attribute data from node
long CXMLManager::GetIntegerAttribute(
    // The node from which to extract the attribute
    MSXML::IXMLDOMNode* pNode,     
    CString attName  // Attribute name
);
double CXMLManager::GetDoubleAttribute(
    MSXML::IXMLDOMNode* pNode, 
    CString attName
);
CString CXMLManager::GetStringAttribute(
    MSXML::IXMLDOMNode* pNode, 
    CString attName
);

Data storage:

// Create XML node
MSXML::IXMLDOMNode * CXMLManager::CreateDOMNode(
    // The XML document where to create the node
    MSXML::IXMLDOMDocument* pDoc, 
    int type,             // Node type
    CString nodeName        // Node name
);
// Three functions to strore data in sttributes
CXMLManager::SetIntegerAttribute(
    MSXML::IXMLDOMNode* pNode, // Pointer to the node where to store data
    CString attName,         // Attribute name
    long val            // The value
);
CXMLManager::SetDoubleAttribute(
    SXML::IXMLDOMNode* pNode, 
    String attName, 
    double val
);
CXMLManager::SetStringAttribute(
    MSXML::IXMLDOMNode* pNode, 
    CString attName, 
    CString val
);

Example of usage

MSXML::IXMLDOMDocument *pDoc = NULL;
    CoInitialize(NULL);
    // Create the document 

    CHECKHR(CoCreateInstance(MSXML::CLSID_DOMDocument, 
                              NULL, CLSCTX_INPROC_SERVER,
                              MSXML::IID_IXMLDOMDocument, (void**)&pDoc));
    // Load the document contents from file
    CHECKHR(xmlManager.LoadDocument(pDoc,"C:\\Test.xml"));
    // Create new node

    MSXML::IXMLDOMNode *pNode = pNode = xmlManager.CreateDOMNode(
        pDoc,MSXML::NODE_ELEMENT, "New Node");
    // Add string to the node 
    xmlManager.SetStringAttribute(pNode,"String","Sample data");
    // Add integer to the node 
    xmlManager.SetStringAttribute(pNode,"Integer",56872);
    // Add double to the node 
    xmlManager.SetStringAttribute(pNode,"Double",35.264);


    // Append the new node to the document
    pDoc->appendChild(pNode, NULL);
    // Save the updated XML document to file
    xmlManager.SaveDocument(pDoc,,"C:\\Test.xml"));
