I'm using TinyXml2 v8.0.0 to create an XML buffer to send to an API. The example includes a declaration. I'm implementing this with:

XMLDocument doc;
doc.InsertEndChild(doc.NewDeclaration());
XMLElement* pRoot = doc.NewElement("Stuff");
doc.InsertFirstChild(pRoot);

The documentation for NewDeclaration states:

If the 'text' param is null, the standard declaration is used.:

`<?xml version="1.0" encoding="UTF-8"?>`

You can see this as a test in https://github.com/leethomason/tinyxml2/blob/master/xmltest.cpp#L1637

But when I print the buffer out the declaration has been placed at the end of the buffer after a newline:

<Stuff>
</Stuff>

<?xml version="1.0" encoding="UTF-8"?>

Does anyone know why this is happening? I'd expect it to be at the start of the buffer with no newline.

CodePudding user response：

Presumably, that's because you told it to put the declaration as the EndChild and the Stuff element as the FirstChild.
