xModify 介绍
xModify is an XML syntax that can be used to update HTML elements
declaratively. This means that developers can utilize server-side frameworks
to create xModify documents that an xModify Processor will use to update the
HTML document.
Why is this Helpful?
Because, instead of having to create JavaScript to update the UI for a
particular dataset, the developer
can use server-side functionality such as PHP, J2EE, Ruby, or XSLT to create
XML documents that can to the same thing. This
typically will save code, time and increase the maintainablity of the
application.
The second reason xModify is helpful is that it puts the know-how into a well
defined XML layer, instead of either a
client-side or server-side library. XML can be outputted from any server-side
or processed client-side layer, making it more likely that knowledge of
xModify can be leveraged across projects.
Operations
xModify contains a set of operation that a developer would need to perform
when manipulating a XML or HTML DOM.
Each of the operations contains a select attribute that is used to select a
set
of operations.
- append
Append the children of the operation to the selected nodes
- clone
Create a clone of the selected nodes.
- insert-after
Insert the children of the operation after the selected nodes
- insert-at
Insert the children of the operation at a specific index of the selected nodes
- insert-before
Insert the children of the operation before the selected nodes
- remove-attribute
Remove an attribute from the selected nodes
- remove-element
Remove the selected nodes.
- replace
Replace the selected nodes with the children of the operation.
- replace-children
Replace the children of selected nodes with the children of the operation.
- set-attribute
Change an attribute of the selected nodes.
- set-innerhtml
Change the HTML of the selected nodes to be the children of the operation.
- embed-xal
Embed XAL components of the operation into the selected nodes.
