input Fields with XML_问答_开发者_运维开发者技术经验分享

I am 开发者_高级运维writing a Page with XML Only. No XSL is being. everything is going well with XML and CSS. But how can I make Input fields with XML and CSS Only ?? is it really possible ??

Xml is for data transformation, porting, trasportation, etc - things related to data.

CSS is for styling.

You will need something for instance, html(or XForms?), to provide/render controls.

Or probably, if you plan to render the control yourself, then you can, for instance, add an element, and render the control by parsing it yourself.

<MyControl type="Text">This is a test value</MyControl>

When you see MyControl having a Text type then add a Text control.

--EDIT--

This is in response to your comment.

I understand what you are saying; to be clear, I believe CSS by nature/actually is for styling - therefore CSS is applied "on" the controls, CSS aren't the controls; so we come up with certain classes, ids, selectors and apply them over the controls.

This may be, yet again, a fat example, but its like telling a "Paint" to build a "House".

Probably you already know this, but this is just to add: Following is how CSS is applied to a html button control. Example taken from here:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>CSS Button</title>
<style type="text/css">
body {
  font: 140%/1.6 "Gill Sans", Futura, "Lucida Grande", Geneva, sans-serif;
  color: #666;
  background: #fff;
}

a:link, a:visited {
  display: block;
  width: 6em;  
  padding: 0.2em;
  line-height: 1.4;
  background-color: #94B8E9;
  border: 1px solid black;
  color: #000;
  text-decoration: none;
  text-align: center;
}

a:hover {
 background-color: #369;
 color: #fff;
}

</style>
</head>

<body>

<p><a href="#">Button</a></p>

</body>
</html>

The above code is going to render a button with css applied like following: alt text http://img689.imageshack.us/img689/4615/72060104.jpg

So to answer your question directly, I believe it is not possible to render a control with CSS.

Now based upon your requirements, I understand that: 1. You want to render the control yourself. 2. You want to apply CSS to that control.

Solution 1: 1. Add, parse and render your custom control xml tags, as discussed earlier. 2. And add the CSS style within xml, see example

Solution 2: 1. Add, parse and render your custom control xml tags, as discussed earlier. 2. Add css in xml CDATA; while xml parse, grab the CSS from CDATA, and apply to the control.

I don't believe you can use just CSS to create controls.

However..

If you don't mind expanding to use something else, I would suggest using XForms. It works very well with XML, and it uses CSS for styling.

The following are links to some guides, tutorials, and articles to get you started:

http://en.wikibooks.org/wiki/XForms

http://w3schools.com/xforms/default.asp

Hope this helps!

CSS can style XML, but browsers are inconsistent concerning semantics.

For example, something like:

<Link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:type="simple" xlink:href="..." />

Will make a working link in Firefox, but doesn't work in Safari. ( I think it also worked in IE, but I tried it a long time ago, so I could be wrong. I also tried using <xhtml:a ...> , which I think also worked in some but not other browsers. Perhaps there's a way to do this in javascript. )

So: there's not even a portable way to get link behavior in CSS styled XML. I don't think input fields are possible at all. Doing xslt transforms to html in the browser is much more portable. You might also look at XForms -- although no browsers support that natively either.
