在客户端使用JavaScript通过XSD验证XML [英] Validate XML against XSD with JavaScript on client side

问题描述

我需要以友好的方式向用户显示XMLfile，因此我正在创建树状结构，例如: http://thecodeplayer.com/walkthrough/css3-family-tree ，而不是向用户显示原始XML.

I am required to show a user an XMLfile in a friendly way as a result I am creating a tree like structure such as: http://thecodeplayer.com/walkthrough/css3-family-tree instead of showing the user the raw XML.

现在，当创建一个新节点时，我正在服务器端对其进行验证.如果服务器验证了新提议的XML(tree)，那么我将继续创建一个新节点.

Right now when creating a new node I am validating that on the server side. If the server validates the new proposed XML(tree) then I go ahead and create a new node for example.

无论如何，现在我想允许用户拖动这些节点.当拖动节点时，如果我在服务器端验证了提议，那将会很慢.所以我的问题是如何针对客户端的架构验证XML文件，这样，在拖动节点时，我可以根据验证是否成功来允许拖动节点.

Anyways now I will like to allow the user to drag these nodes. When dragging the nodes if I validate the proposed on the server side it will be to slow. So my question is how can I validate an XML file against a schema on the client side so that when dragging a node I can allow dragging the node or not depending whether or not the validation succeeds.

推荐答案

请参见 xml.js 程序包，该程序包会导出通过 libxml2 .

See the xml.js package, which exports an xmllint object ported via Emscripten from libxml2.
