Internet Explorer makes it easy to transform the XML document with the XSLT with only a few lines of code. We use the transformNode() method, which takes the XML and XSLT documents and combines them in one step:

We first check to see if the browser supports the transformNode() method. We ve done this here by testing for ActiveX object support. If it supports it, we call the transformNode() method on the global variable containing our XML data, passing it the global variable containing our XSLT data. The result of this transformation is added to the innerHTML of our result element, which then contains the newly formatted search results. Now that we are able to format the results for Internet Explorer, let s get this functioning for Mozilla-compatible browsers.

With Mozilla, we need to use the XSLTProcessor object, which lets us combine the XML and XSLT documents. Note that even though Opera and Safari both support the XMLHttpRequest object, they still do not support the XSLTProcessor object, and they cannot run this project without support from the server (we will address this issue in section 12.5.2). In the listing 12.8, we transform the XML document using the XSLT and display the formatted result set.

The first step is to initialize the XSLTProcessor object, which enables us to join the XML and XSLT files together. The importStylesheet method of the XSLTProcessor object allows us to import the XSLT file so that we can join it to the XML file in the upcoming steps. When the XSLT file is loaded into the processor, we are left with transforming the XML document. The XSLTProcessor is used again with a new method called transformToFragment(). The transformToFragment() method takes the XML file and combines it with the XSLT, and then returns the formatted result tree. We replace the content that exists in our result element by setting the innerHTML with a blank string. This removes our loading animation from the

page. Finally, we take the result we obtained from the transformToFragment() method and append it to the element. The newly formatted search results are now displayed to the user. This code introduced some new concepts to us, including the XSLTProcessor object, which allows us to combine arbitrary XML and XSLT files. The Mozilla and Firefox browsers require us to use more DOM methods to combine the two documents. Internet Explorer, on the other hand, required only a single line of code to transform the XML document. The overall end result is exactly the same: they both show our results formatted according to the XSLT file. Now that the client-side code is finished, we can save our documents and run a test of our live search. Enter some text into the textbox, and click the search button. The results should appear in the table format shown in figure 12.4. As you can see, we have finished building our XSLT document and were able to run a successful search. The table displayed in figure 12.4 is rather dull since it has no formatting. That means the only thing that we have left to do is style our results table to make it more visually appealing. To do that, we need to use Cascading Style Sheets (CSS).
12.5 Completing the search
Now that we have combined our XML and XSLT documents to get our results, we need to enhance the style of the search results by applying CSS to our elements. Styling the elements will make it easier for the users to read the results. The first step in improving the user experience is to apply our CSS rules to the HTML elements.
