308 CHAPTER 10 USING FLASH TO DISPLAY XML If a title exists, the code creates a new element and adds an idattribute: var newDVD:XMLNode = oXML.createElement(”DVD”); newDVD.attributes.id = rootNode.childNodes.length + 1; It sets the value of the attribute to one more than the number of elements in the XML tree. The next code block creates a new element and uses appendChild() to add the text from the title_txt component: var newDVDTitle:XMLNode = oXML.createElement(”title”); newDVDTitle.appendChild(oXML.createTextNode(title_txt.text)); newDVD.appendChild(newDVDTitle); The code repeats this process for the<br />
<format> and <genre> nodes: if (format_txt.text.length > 0) { var newDVDFormat:XMLNode = oXML.createElement(”format”); newDVDFormat.appendChild(oXML.createTextNode(format_txt.text)); newDVD.appendChild(newDVDFormat); } if (genre_txt.text.length > 0) { var newDVDGenre:XMLNode = oXML.createElement(”genre”); newDVDGenre.appendChild(oXML.createTextNode(genre_txt.text)); newDVD.appendChild(newDVDGenre); } Finally, the code appends the <DVD> element to the root node, reloads the List component, and clears the values in the text field: rootNode.appendChild(newDVD); loadList(null); clearTextInputs(); Editing an existing node uses a different block of code that s easier to interpret. First, the code finds the child node index for the selected node so it can select the node again after the update: var selectedNodeIndex:Number = Number(selectedDVDNode.attributes.id)-1; Then it checks whether appropriate text has been entered into the TextField component and changes the nodeValue accordingly: if (title_txt.text.length > 0) { selectedDVDNode.childNodes[0].firstChild.nodeValue = title_txt.text; } if (format_txt.text.length > 0) { selectedDVDNode.childNodes[1].firstChild.nodeValue = format_txt.text; } if (genre_txt.text.length > 0) { selectedDVDNode.childNodes[2].firstChild.nodeValue = genre_txt.text; } <br />Searching for affordable and proven webhost to host and run your servlet applications?
