Zope Version (Zope 2.10.3-final, python 2.4.3, linux2) using zeo storage I am trying to implement a server side XSL Transform with the tools I have installed. I have 4suite, libxml2, and libxsl. The all of the files are dtml documents. Listing 1 below works on the command line and writes an html file named 'foo' to the file system. So I added a def, a parameter to receive, and indent Listing 1 appropriately to run as an External Method. I also found, from this list in September 2006, an almost identical External Method using parseDoc instead of parseFile, and SaveToString instead of SaveToFile, see Listing 2 and the traceback that follows it. All combinations and attempts to use an External Method result in either parseDoc or parseFile failing. Also, the Zope server will not respond to WEB clients for as long as it is trying to process the External Method and Apache times out in about 100 seconds with a Proxy error and I usually have to restart the Zope server to get access back to it through a WEB client although ps doesn't show any unusual processor or memory usage. I have tried using Listing 1 and then read the file back in to return the html text but still get the same result, parse failed. The test page, a dtml document, making the call only contains: <dtml-call "C_xml2html('<dtml-var 0418rice.xml>')"> or <dtml-call expr="C_xml2html('<dtml-var 0418rice.xml>')"> Thanks for any help, Thomas Listing 1---- command line python script that works ******************** import libxml2 import libxslt myxml="http://www.library.appstate.edu/appcoll/ead2002/0418rice.xml" styledoc = libxml2.parseFile("http://www.library.appstate.edu/appcoll/ead2002/styles/eadbase.xsl") style=libxslt.parseStylesheetDoc(styledoc) doc=libxml2.parseFile(myxml) result=style.applyStylesheet(doc, None) style.saveResultToFilename("foo",result,0) style.freeStylesheet() doc.freeDoc result.freeDoc() Listing 2 ---- External Method python script ********************** import libxml2 import libxslt stylestring = file("/var/zope/Extensions/eadbase.xsl").read() def xml2html(xmlfile): styledoc = libxml2.parseDoc(stylestring) style=libxslt.parseStylesheetDoc(styledoc) doc=libxml2.parseDoc(xmlfile) result=style.applyStylesheet(doc, None) html=style.saveResultToString(result) style.freeStylesheet() doc.freeDoc result.freeDoc() return html Traceback from the call using Listing 2 2007-10-24T16:29:56 ERROR Zope.SiteErrorLog http://www.library.appstate.edu/appcoll/ead2002/0000_xmlxsltest.html Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module OFS.DTMLMethod, line 144, in __call__ - <DTMLMethod at /appcoll/ead2002/0000_xmlxsltest.html> - URL: http://www.library.appstate.edu/appcoll/ead2002/0000_xmlxsltest.html/manage_... - Physical Path: /appcoll/ead2002/0000_xmlxsltest.html Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: C_xml2html Module <string>, line 1, in <expression> Module Products.ExternalMethod.ExternalMethod, line 231, in __call__ - __traceback_info__: (('<dtml-var 0418rice.xml>',), {}, None) Module /var/zope/Extensions/xmlxsltests.py, line 11, in xml2html Module libxml2, line 1224, in parseDoc parserError: xmlParseDoc() failed -- ==================================================================== Thomas McMillan Grant Bennett Appalachian State University Operations & Systems Analyst P O Box 32026 University Library Boone, North Carolina 28608 (828) 262 6587 They say a picture is worth a thousand words.
