Source Code Listing

// Scan crisp.xml for ArticleTitles and 
// create another XML document containing
// only the titles.
void ScanForArticleTitles1(void)
    {
    // Load the input document.
    CkXml xml;
    xml.LoadXmlFile("crisp.xml");

    // Create the output XML document in-memory
    CkXml outXml;
    outXml.put_Tag("article_titles");

    // Iterate over ArticleTitle tags regardless of where
    // they occur in the document. Setting the first parameter
    // to 0 causes the search to begin from the document root.
    CkString strContent;
    CkXml *node = xml.SearchForTag(0,"ArticleTitle");
    while (node)
	{
	// NewChild returns the created child, whereas NewChild2 does not.
	node->get_Content(strContent);
	outXml.NewChild2("article",strContent.getString());

	// Search for the next ArticleTitle tagged node beginning with the node
	// just after the current node in a breadth-first document tree traversal.
	CkXml *curNode = node;
	node = xml.SearchForTag(curNode,"ArticleTitle");
	delete curNode;
	}

    outXml.SaveXml("ArticleTitles1.xml");
    return;
    }
