| Abstract | On the web, static pages fade into the past; web sites use server and client-side scripting techniques to improve the user experience. For client-side scripting, JavaScript is by far the most commonly used dynamic language. In these scripts, regular expressions are widely used for several purposes, e.g., for text filtering and form validation. In this paper, we take a closer look at regular expressions on the web. We investigate historical data and determine the trends of the use of regular expressions over time on various web sites. Then, we also take a snapshot of the current status. We find that although regular expressions are being used more and more often, their use is highly repetitive: on the most popular web sites only 4% of the regular expressions are unique. Based on this result, we show that web browsers can cut down regular expression compilation time to the third by applying caching techniques. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
