Hello,
I use XML documents quite often. The XMLDocument class in Elements / RTL does not seem to have a constructor. How do I go about creating a new XMLDocument?
Thank you,

It has factory methods, because .ctors would have been to limited in regards to what overloads can handle (ie, would new XmlDocument(string)
take a filename or an XML string?). Look for the static From*
and TryFrom*
methods.
If we ever add support for multiplee named .ctors with the same parameters, on .NET, I might add .ctors as well. (eg new XmlDocument withString()
, new XmlDocument withFile()
, etc).
I guess I’m not understanding. I want to create a completely new XML document if one does not exist.
For example, how do I do the equivalent of:
XMLDocumet document = new XMLDocument();
if (file.exists(filename))
document.Load(filename);
// read / edit the document
document.Save(filename);
Do I pass an empty string to the From* and TryFrom* methods?
Do I have to pass it a string, such as XMLDocument document = XMLDocument.From("<?xml version="1.0" ?>")?
Well, an “empty” xml document would be invalid, you gotta start with something. So either WithRootElement
ir FromString
can work, depending on what’s more convenient; WithRootElement
can take an XmlElement
instance or just a name for the root element.
