I want to write a script which has one part of its function to log certain messages to an xml file. Each time the script is run, it will add a few tags. for example, <Message>...</Message> for each message. Of course, it will have to have tags around the whole file, such as <Messages>...</Messages>. My query is this: How would I discard the last line of the saved file before writing the new tags? The closing tag would then be added back on.

Thank you,

err why not use the XML com object?

code:

---

var xml = new ActiveXObject("Microsoft.XMLDOM");
xml.load("filename of xml here");

//create the element to be added
var toAdd = xml.createElement("test");

//add a message to it
toAdd.appendChild(xml.createTextNode("testing this"));


//add it into our xml
xml.getElementsByTagName("Messages")[0].appendChild(toAdd);


//save our xml
xml.save("filename of xml here");

Thank you for your help.

How would I add more than one child to a parent tag at once. For example, to add the following to an XML file for every message received:

<Message>
          <Sender>Test</Sender>
          <Text>Test Text</Text>
</Message>

Hope you can help,

Edit: I've managed to do this, but the children are always added to the same parent, instead of new ones. How would I retrieve the number of <Message> tags in the file?

code:

---

var IntMessagesLen = xml.getElementsByTagName("Messages").length; //How many <Message></Message> pairs
xml.getElementsByTagName("Messages")[IntMessagesLen - 1]; //This will do nothing, but you can append any function you want to do on the object (which is the last <Message></Message> pair contained in the xml file.

Hope this helps
