XmlAttributeCollection initialization in AL

dreez

Hello,

I would like to use XmlAtributeCollection, but I have no idea how to initialize it.

Here's my sample code:

var
    XmlAttrCol: XmlAttributeCollection;
begin
    XmlAttrCol.Set('attr1', 'value1');
    XmlAttrCol.Set('attr2', 'value2');
    XmlAttrCol.Set('attr3', 'value3');
    XmlAttrCol.Set('attr4', 'value4');
end;

I am getting an error:

Microsoft.Dynamics.Nav.Runtime.NavXmlAttributeCollection was not initialized.

But there is no such method to initialize XmlAttributeCollection...

I have also tried following code:

var
    XmlAttrCol: XmlAttributeCollection;
    XmlElem: XmlElement;
begin
    XmlAttrCol := XmlElem.Attributes();
    XmlAttrCol.Set('attr1', 'value1');
    XmlAttrCol.Set('attr2', 'value2');
    XmlAttrCol.Set('attr3', 'value3');
    XmlAttrCol.Set('attr4', 'value4');
end;

but with the same error...

Any help, please?

Okay, I got it...
The thing is, that you have to create the XmlElement first, then the second variant works. so...

var
    XmlAttrCol: XmlAttributeCollection;
    XmlElem: XmlElement;
begin
    XmlElem := XmlElement.Create('sampleElement');
    XmlAttrCol := XmlElem.Attributes();
    XmlAttrCol.Set('attr1', 'value1');
    XmlAttrCol.Set('attr2', 'value2');
    XmlAttrCol.Set('attr3', 'value3');
    XmlAttrCol.Set('attr4', 'value4');
end;

...works fine.
