I using the net diagram in JavaApplet mode. I want to get diagram XML by JavaScript on client-side.
The folowing code is working. But return empty. What am I doing wrong?

<script language="javascript">
function btnExport_click()
{
var doc = new ActiveXObject('Microsoft.XMLDOM');
document.getElementById('DiagramView1').getDiagram().saveToXml(doc);
alert(doc.xml);
}
</script>

why doc.xml is empty?

Hi,

The saveToXml method expects a Java org.w3c.dom.Document object rather than an ActiveX Microsoft.XMLDOM one. You could use the Diagram.saveToString method to get the XML as a string, and then parse that string using any XML DOM API if you need access to individual elements.

I hope that helps,
Stoyan

hi Stoyan:

Thank you for your reply!
But I found that if the Chinese characters included, xml will appear garbled.
How I solve them?

Javascript Code is as follows:

var doc = new ActiveXObject('Msxml2.DOMDocument');
doc.loadXML(getApplet().getDiagram(false));
alert(doc.xml);

Hi,

This worked fine in our test:
Code
Select All
function test()
{
	var applet = <%= diagramView.AppletElement %>;
	var diagram = applet.getDiagram();

	// Base64 = 1;
	// Xml = 2;
	// CompressedXml = 3;
	var xml = diagram.saveToString(2, true);
	alert(xml);
}




I hope that helps,
Stoyan

hi Stoyan
    I do so in accordance with your method, but the Chinese characters are still garbled.
   My test Page has been sent to your mailbox(support@mindfusion.eu).
    Please help me solve this problem.
    thanks a lot!

Hi,

I can see the Chinese characters ok in the text area:


Is the encoding attribute on the first line of the text area set to "UTF-16" after you press the save button? I think we set UTF16 as default encoding in one of the recent releases; if you get a different one, try that with version 3 of the control:

I haven't changed anything in the pages you sent me. Are you using NetDiagram V3?

Running on my computer, click the savetostring button to generate the xml data is always utf-8 format, rather than utf-16 format.
I think it was caused by this reason,How can I do to utf-16 format to generate data?

Do the characters appear correctly in the text area if you write something in Chinese there?
