Text analysis tools for XML documents using regular expressions &XSL a Web application Karthik Jayaraman Colgate University, Hamilton, USA kjayaraman@mail. colgate.edu Alexander Nakhimovsky Computer Science Dpt, Colgate University, Hamilton, USA sasha@cs.colgate.edu Abstract: A common type of a text-analysis query is determined by several parameters, such as: lexical material to search for; the documents to search; the ranges of text to search within the documents; the analytical operation to perform, such as frequency count or concordance; if context is requested, the way to measure the amount of context. We say that a text-analysis tool is"markup-aware if both query conditions and context can be expressed in terms of markup. Most markup-aware text-analysis tools are based on SGML-TEI; none of them, to the best of our knowledge, are Web applications, and none use XSLT and XPath, two new languages codified by W3CinNovember 1999. This paper describesa project with the following design goal: They are Webapplications, in the sense that their user interface isa Web browser and they can be accessed over the any TCP/IP network. They can process queries containing both text patterns (described by regular expressions) and markup patterns (described by XPathexpressions). They are DTD-independent, in the sense that user interface is constructed programmatically on the basis of the documentsDTD. They are extensible in the sense that they can be extended by code written in a general-purpose programming language (Java most easily). The last item is for those queries that would be difficult or impossible to express as an XSLT template. Fortunately, many XSLT processors, including James Clarksxtwhichweare using, providea mechanism that makes it possible to run arbitrary Java code (packaged asa Java bean) from within xtandfeedthe resulting node-setback into xt. We have, in effect, aTuringmachine, ready to compute anything compu ...
