API should support an input string

[sosna]

Thanks for this nice library :).

I see the method mapSDMXMLResponse expects a DOM object as input. Could the library also accept a string as input and internally build a DOM object out of it? That would ease the work of the clients a bit. Thanks!

Thanks!

It looks like this could be possible as you should be able to parse XML from a string using the parseFromString method from the DOMParser object. All relatively recent browsers should support this.

var parser = new DOMParser();
var doc = parser.parseFromString(stringContainingXMLSource, "application/xml");

Also looks like DOMParser is supported for Node in this package: https://www.npmjs.com/package/xmldom.

DOMParser is now used internally to convert the xml source to document object. Native DOMParser in the browsers and xmldom DOMParser in Node.

Turns out that xmldom does indeed work very well for this use case but it is not 100% compatible with DOM and JSDOM. For example:

• getElementsByTagNameNS works differently when passing null as the namespace.
• attributes are not accessible by name (like element.attributes.foo)
• getAttribute returns empty string if attribute does not exist
• childNodes return null if element does not have children
• childNodes may include more nodes (extra text nodes)

However all in all a very nice library
