问题
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.
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.
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.
回答1:
See the xml.js package, which exports an xmllint object ported via Emscripten from libxml2.
