(MFC) AddAttribute - Insert New Attribute in an XML NodeDemonstrates adding an name=value attribute to an XML element.
This example uses the XML sample file here: sample1.xml. The sample1.xml file contains this content:
#include <CkXml.h> void ChilkatSample(void) { CkString strOut; CkXml xml; bool success = xml.LoadXmlFile("qa_data/xml/sample1.xml"); if (success != true) { strOut.append(xml.lastErrorText()); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } // Navigate to the "books" element: bool bFound = xml.FindChild2("books"); if (bFound == false) { strOut.append("No books child found!"); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } int numChildren = xml.get_NumChildren(); int i = 0; while (i < numChildren) { // Navigate to the Nth book xml.GetChild2(i); // Display the book title: strOut.append(xml.getAttrValue("title")); strOut.append("\r\n"); // Add a new integer attribute: // Should never fail.. xml.AddAttributeInt("bookId",i); // Add a new unread="yes" attribute: xml.AddAttribute("unread","yes"); // Navigate back up to the parent: xml.GetParent2(); i = i + 1; } // Navigate back to the document root: xml.GetRoot2(); // Save the updated document: success = xml.SaveXml("modified.xml"); if (success != true) { strOut.append(xml.lastErrorText()); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } strOut.append(xml.getXml()); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); } |
