try to recurse the DOM Tree to collect all nodes.........

 

Like ................

 

 

bool CXMLReaderClass::ReadFromXmlDOMReader()

{

       // m_ptrXMLDoc - Collected earlier by xmlParseFile/Memory() API 

       // m_ptrXMLRootNode - Collected earlier by
xmlDocGetRootElement(m_ptrXMLDoc);

       if ( !m_ptrXMLDoc || !m_ptrXMLRootNode)

              return false;

 

       xmlNodePtr ptrCurrXMLNode;

       ptrCurrXMLNode = m_ptrXMLRootNode;

 

      // Skip from Root Node to its 1st child node

       ptrCurrXMLNode = ptrCurrXMLNode->children;

       while( ptrCurrXMLNode )

       {

              TraverseXmlDOMReaderTree( ptrCurrXMLNode );

              // Skip to next sibling

              ptrCurrXMLNode = ptrCurrXMLNode->next;

       }

 

       return true;

}

 

 

void CXMLReaderClass:: TraverseXmlDOMReaderTree ( xmlNodePtr
pXMLCurrNode )

{

      // Ignore TEXT Nodes as most of them are empty

      if ( pXMLCurrNode->type == XML_ELEMENT_NODE )

      {

         // Get the node u need

         // Get Attributes of  the current node

      }

 

       // Traverse till the last child of the current node

       pXMLCurrNode = pXMLCurrNode->children;

       while ( pXMLCurrNode )

       {

              TraverseXmlDOMReaderTree ( pXMLCurrNode );

              pXMLCurrNode = pXMLCurrNode->next;

       }

}

Subject: [xml] How to iterate through...

 

I brought a piece of XML file that I'm trying to parse it and somehow I
stuck to find a way to iterate through them and collect the properties
in each line(element) 





I tried to use    print_element_names()  function in sample code but had
no success. I can get the 'element_x' and their properties in first line
below but from that point don't know how to iterate to its nested
element(section_1) and further and collect them all. 





Any help greatly appreciated,





Thanks, 

Nima





<element_x prop_1="value1" prop_2="val2" prop_3="val_3" >

            <section_1>

                        <elem_1 category="&lt;CompanyName>"
qualifier="Is">company1</elem_1 >

                        <elem_2>doc1.pic</elem_2 >

                        < elem_1 category="&lt;CompanyName>"
qualifier="Is">Company2.</elem_1 >

                        < elem_2 >doc2.pic</elem_2 >

                        < elem_1 category="&lt;CompanyName>"
qualifier="Is">Company3</elem_1 >

                        < elem_2 >doc1.pic</elem_2 >

                        < elem_2 >doc3.pic</elem_2 >

            </section_1>

</element_x >
