How to convert XML to JSON by using JavaScript or Java?

<p>&nbsp;</p><p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;">Over the last years the simple data format JSON had a great inpetus in the service-oriented architecture and especially in the area of internet services. It is widely used because of its compactness and easy understandability.</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px;">&nbsp;</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;">JSON is lightweight and was used for several of my projects. However, the convertion by hand (Or by an own routine) is an unacceptable quality problem.</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px;">&nbsp;</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;">A transformation could look like the this example:</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px;">&nbsp;</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;">The&nbsp;<strong>XML </strong>of image xml.png&nbsp;<span style="font-family: 'Trebuchet MS', sans-serif; font-size: 13px;">should be transformed to the&nbsp;<strong>JSON</strong> representation of image json.png.</span></p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 13.0px 'Trebuchet MS'; min-height: 15.0px;">So to a simple representation using curly braces.</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; line-height: 21.0px; font: 13.0px 'Trebuchet MS';"><span style="font-family: Helvetica, sans-serif; font-size: small;"><span style="font-size: 12px;"><span style="font-family: 'Trebuchet MS', sans-serif; font-size: small;"><span style="font-size: 13px;"><br /></span></span></span></span></p><p style="margin: 0.0px 0.0px 0.0px 0.0px; line-height: 21.0px; font: 12.0px Helvetica;">JavaScript could be used to convert the data before it is passed on to the Java application. The conversion could also be done in Java itself.</p><p>&nbsp;</p>

Simile timeline

Timeline is a DHTML-based AJAXy widget for visualizing time-based events
It provides bifocal-view, with variable granularity of the detail view (within one timeline!). User navigates intuitively by panning horizontally over one of the two time-ribbons. It requires zero installation, data input is simply by pointing to a xml file.
Drawback: In some cases it would be nice to be able, to connect events, to express some kind of relation.

How to execute MySQL Statements within JavaScripts with AJAX

Currently i am developing an administration software for a physiotherapy center. Therefor i simply use PHP and MySQL, so XAMPP was a very comfortable solution. As the complexety of the system grows i had to broaden my horizon and find some tricky solutions to achieve the surreal requirements of my employer. People always want everyhing "flexibel", fast, "automatically",... properties which are very hard to reach within a software. So someday i encountered a very hard problem which took me a long time to solve it (although, afterwards it wasn't so difficult). I had to process some data within my database, which was generated and accessed via JavaScript. If someone has programmed a little bit with PHP before, its not that hard to get content of a PHP-Variable within JavaScript, but its not so easy to process some JavaScript-Variables within an MySQL Statement without reloading the page. So a solution had to be found. After hours of internet surfing and talking to some programmers i found it, my holy grail, AJAX.
