[xquery-talk] [ANN] XQuery as a scripting language in IE

[daniela florescu]

Dear all,

we are happy to announce the public release of XQiB,  a plugin for  
Internet Explorer which allows the execution of client-side XQuery to  
navigate and update the browser’s internal DOM. This plugin allows to  
execute XQuery in the same way as JavaScript. However, the resulting  
code is more elegant because there’s no data model mismatch. For  
example, opening an alert window that shows the text of the first H1  
element of the current site is as simple as that

declare function local:main() {
   browser:alert ( fn:data( ( //H1 )[1] ) )
};

Note that the browser plugin provides a rich set of functions to  
accomplish things as showing alert windows or modifying styles.

XQiB is based on the Zorba XQuery processor. Specifically, XQiB is an  
implementation of the Zorba Store API and implements a set of browser- 
specific functions such as the alert function and a variety of other  
AJAX functions (e.g., drag & drop, window controls, asynchronous REST  
calls, etc.). The implementation of the Store API essentially  
encapsulates the browser’s DOM and therefore delegates accessor and  
updating function calls on the XDM to the DOM.

Zorba’s powerful function library (e.g. REST functions), the  
implementation of various XQuery-related specifications (e.g. XQuery  
Updating Facility), and a variety of language extensions (e.g. eval)  
make it a pleasure to develop rich internet applications.

If you want to learn more about XQiB, are interested in playing around  
with it, or would like to contribute to the project, please visit http://www.xqib.org/ 
.

A similar Firefox plugin is under construction.

The XQIB team
