Alden believes that getting electronic data correct at source is the best solution to quality control. We have developed our own customizable quality control software application for checking and correcting structure and content errors within XML and SGML encoded texts. The main parser component includes three XML parsers and one SGML parser; parsing and correcting either in batch or single file mode; the drag and drop of files; positioning at each error and allowing the correction and re-parsing; and allows the user to set rules for checking the content of text.

Other components within the suite include: DTD and schema analysis, allowing the building of lists of elements, attributes and entities, and drill-through capability using a complex tree-view; building catalogue files; a batch module that processes any number of structured files - checks folders, sub-folders, and allows the use of watch folders; and an integrated text editor.
