JChemTidy: A tool for converting chemical Web document collections to an XHTML representation

A robot-based procedure is described for traversing a collection of hyperli nked documents written in HTML and converting these to the XML-compliant an d well-formed XHTML representation. Transcluded chemical content invoked us ing <embed> or <applet> HTML calls are converted to the XHTML recommended < object> form. Additional attributes such as title or derived chemical attri butes such as a SMILES descriptor are added to improve the indexing of the resulting document collection.
