 Maybe you find useful the following work about document transformations. I think authors provide with some discussion about the dichotomy between procedural and declarative transformations (apart of giving an in-depth overview of transformation techniques, mainly based on formal work on translation theory): ftp://cs-archive.uwaterloo.ca/cs-archive/CS-95-46/CS-95-46.ps.gz By the way, I don't think in XSLT as 'purely declarative', because you explicitly use control directives in terms of 'xsl:apply-templates' elements (assuming that you are not using a more programmatic style in terms of named templates). In the pointed work you will find truly declarative approaches, unfortunately only applicable under more or less strong assumptions about the involved input and result languages. In my opinion, I think a distinction between 'domain-specific languages for document transformation' and general-purpose languages equipped with facilities for document manipulation could be more meaningful that the more fuzzy 'declarative-procedural' taxonomy.

There exist non-procedural languages such as XSLT to do this by "declaring" what is to be done, and there exist procedural approaches -- such as DOM+Javascript, OmniMark, XMLPerl, PHP (?), and perhaps XSLScript > -- that let you write a script to just *do* what needs to be done. ....... -- Jose-Luis Sierra-Rodriguez ------------------------------------------------------------ Dpto.
