Summary
LURE is an attempt to implement a hybrid xml/html DOM parser and renderer for the Love2d game engine. The goal of LURE is to provide the following:
- A non-validating xml/html parser which generates a (somewhat) W3C Standards complaint DOM Object for use with love.
- A html renderer which will display html markup in the love window.
Although we have a working prototype of the xml/html parser and DOM Object, we do not yet have a working renderer. Given the sheer size of the W3C DOM specification, this area will serve to document and track the current status of DOM Interface implementations.
LURE DOM Reference
| Object | Description |
|---|---|
| DOM Node | The Node object represents a single node in the document tree |
| DOM NodeList | The NodeList object represents an ordered list of nodes |
| DOM NamedNodeMap | The NamedNodeMap object represents an unordered list of nodes. |
| DOM document | The Document object represents the entire XML/HTML document. |
| DOM Element | The Element object represents an element in an XML/HTML document |
| DOM Attribute | The Attr object represents an attribute of an Element object. |
| DOM Text | The Text object represents the textual content of an element or attribute. |
| DOM CDATA | The CDATASection object represents a CDATA section in a document. |
| DOM Comment | The Comment object represents the content of comment nodes in a document. |
| DOM Window | The Window object represents Love window |
xml/html Parser Preview
The parser in its current state implements many of the core DOM node objects. Although the library is not yet ready for prototype release, below is an example of the current xml/html parser and some basic use of the resulting DOM Object.
Below is very simple xml/html markup:
<html>
<head>
<title>Lure Test Page</title>
</head>
<body>
<div id="div1">
this is a sentence<br>separated by a break line.
<div id="div2">Hello</div>
<div id="div3">World</div>
</div>
</body>
</html>
And to parse and work with the DOM in LURE:
require("lure.lua")
htmlDoc = Lure.load("test.html")
print(htmlDoc.getElementById("div1").childNodes[1].data)
--OUTPUT: this is a sentence
print(htmlDoc.childNodes[1].childNodes[2].childNodes[1].childNodes[3].data)
--OUTPUT: separated by a break line.
newElement = htmlDoc.createElement("div")
newElement.setAttribute("id", "myNewElement")
htmlDoc.body.appendChild(newElement)
print(htmlDoc.getElementById("myNewElement").getAttribute("id"))
--OUTPUT: myNewElement
MORE TO COME!
