Shopping different products has become very easy as one can find almost all kinds of products and services through internet. In fact, most of the shoppers feel comfortable in purchasing things online. People do not have time to visit the shops physically and therefore the concept of online shopping has come into the picture. One can get all kinds of details and prices of different products on the websites. The shopping portals are the places where the buyers and sellers meet simultaneously.

In the last few years, the number of internet users has increased significantly. The business opportunities have increased and people have more number of choices. The price comparison websites have emerged due to this trend and they are becoming very popular in a short period of time. These sites provide the customers all the required information at one place and therefore they do not have to visit different portal for this purpose. The 'compare' section is given on these portals so that the users could compare the prices of different brands of products and select the best available deal. All the other information such as reviews, articles, blogs, etc., can be found on these websites which help the customers in making better purchasing decision.

The Price comparison websites are very helpful to the customers as they can keep themselves updated about the upcoming products and services. If one does not visit the websites too often, he or she can get registered with different online price comparison portals. These sites send newsletters, emails and reminders to the customers and deliver the required information to them. In fact, shopping becomes more enjoyable there and the availability of a variety of products make the customers delighted.

In the UK markets, the online are very popular. Yahoo, MSN, Rediff.com, etc., are some of the sites where one can find the facility of comparing the prices of different products. The relatively new portals are also available to the customers where they can get many attractive schemes and deals. The process of booking a product or service is very easy. The shipping cost is automatically calculated and the customer has to just enter the zip code of her or his place. The mobile phones are also used for internet surfing these days. Therefore, they can be used for shopping online as well.

Since online shopping has many advantages, it encourages the customers to explore the options available to them. The online portals offer them the lucrative schemes during the festive seasons. Since the number of visitors gets increased in such times, huge discounts are given to the buyers. With the cut-throat competition prevailing in each industry, it is never easy to find the best products at reasonable prices. The comparison websites help one in comparing different available options and selecting the best possible deals. Different common problems with the physical shopping does not come with the online purchasing. The comparison websites are providing the visitors a lot of entertainment features as well. One can play games, chat online and watch videos on these sites. The facility of selecting the products and putting them in the shopping basket is also provided.

The price comparison sites have given a host of options to the consumers. One can not find so may products or services at any particular shop. The details of the products are also given so that one could know more about the items. Such websites are doing great and they are updated at regular intervals. One can also find the pop-ups, banners, teasers, etc. along with relevant information on these sites by just clicking on the appropriate links. A unique distribution mechanism is maintained by these sites to grow business. As per this mechanism, the merchants give links of their products on different portions of the website. The links are also given in the articles, blogs and reviews. In general, it can be stated that the online shopping brings many innovative facilities to the users and give them a satisfying experience. The features available on these portals are expected to get enriched in the times to come.

Creating a search script isn't an easy task. And it is also very dependent on the site structure you are about to query. The following pages give some ideas on how to proceed.

1: set up the navigation
Define the script name and the commands to be performed on the site to navigate to the results.

<?xml version=" 1.0" encoding=" UTF-8"?>
< webscript name='demo shop sites'>
< gatherdata>
< webcommands name="kelkoo">
setUp value=" http://www.kelkoo.co.uk"/>
beginAt value="/"/>
< setFormElement name=" siteSearchQuery" value=" toilet roll"/>
< submit/>

To find the name of input field, open the page in an HTML editor (we use Mozilla) and click on the INPUT field.

2: Define the result area
First of all visually identify the result area. Then, use an HTML editor to find the exact starting and ending string that defines the result area. Use a regular expression to select the whole area.

Use the group expression (.)* to represent the result area.
< result_selectRegEx>
<![CDATA[
< div class=" mod_std_sub" >(.)*< div id=" pages" class=" pageDiv">
]]>
</result_selectRegEx>

To check the regular expression you typed, use a regex editor (we use the QuickREx eclipse plugin).
Verify that the highlight area is what you expected.

3: Define the result data structure

This step can be tricky.

If the results are included in tables, or in rows of a table, use the corresponding

< result_define_data_structure_as_tables/>

This is the case, but to make an example let's say that we want to define results data structure as regular expression.

< result_define_data_structure_as_regex>
<![CDATA[
< div class=" width">s*
]]>
</result_define_data_structure_as_regex>

This way, we tells to the parsing engine that every result is defined from the matching < div class=" width">s* to the next matching < div class=" width" > s* (we call this a start/end strategy).

It is also possible to define results as group expression (we call this group strategy). Note that it is not easy to balance the tags in HTML using Regex expressions.

4: Upload and run the script

Use the script management menu to upload the script, run it and examine both the whole results and the detailed data parsed.

The whole script that we have created is:

<?xml version=" 1.0" encoding=" UTF-8"?>
< webscript name='demo shop sites'>
< gatherdata>
< webcommands name=" kelkoo">
setUp value=" http://www.kelkoo.co.uk"/>
beginAt value="/"/>
< setFormElement name=" siteSearchQuery" value=" toilet roll"/>
< submit/>
< result_selectRegEx>
<![CDATA[
< div class=" mod_std_sub">(.)*< div id=" pages" class=" pageDiv">
]]>
</result_selectRegEx>
< result_define_data_structure_as_tables/>
< result_setIfNew/>
</webcommands>
</gatherdata>
</webscript>
