[cxml-devel] non-canonical printing
by Cyrus Harmon 07 Apr '12

07 Apr '12

Currently, it seems that non-canonical printing always does this: <foo> bar</foo> Is there an easy way to make that print is <foo>bar</foo>, besides resorting to canonical mode? I can see the case for a new line (and appropriate indentation) for something like this: <foo> <moose> bar</moose> </foo> but I'd still rather see that as: <foo> <moose>bar</moose> </foo> thanks, Cyrus

[cxml-devel] RNG question
by Cyrus Harmon 06 Mar '12

06 Mar '12

So I'm trying to parse a schema that has the following in it: property-attach = element attach { element parameters { fmttypeparam? & encodingparam? }?, value-uri | value-binary } In order to get this to work with cxml-rng, I have to do the following: property-attach = element attach { element parameters { fmttypeparam? & encodingparam? }?, ( value-uri | value-text ) } Is the former invalid RNC or is cxml-rng's parser barfing where it shouldn't? A complete, minimal-ish example is shown below and attempting to parse it gives: failed to parse compact syntax at char 552, file://+/Users/sly/projects/cl-vcard/foo.rnc: Unexpected terminal CXML-RNG::|\|| (value CXML-RNG::|\||). Expected one of: (NIL CXML-RNG::} CXML-RNG::DOCUMENTATION-LINE CXML-RNG::[ :INCLUDE CXML-RNG::IDENTIFIER :START :DIV CXML-RNG::|)| CXML-RNG::CNAME CXML-RNG::|,|) [Condition of type CXML-RNG:RNG-ERROR] Thanks, Cyrus # Hacked together from the RELAX NG Schema for iCalendar in XML default namespace = "urn:ietf:params:xml:ns:icalendar-2.0-hack" value-text = element text { xsd:string } value-binary = element binary { xsd:string } value-uri = element uri { xsd:anyURI } encodingparam = element encoding { element text { "8BIT" | "BASE64" } } fmttypeparam = element fmttype { value-text } property-attach = element attach { element parameters { fmttypeparam? & encodingparam? }?, value-uri | value-text } start = element icalendar { property-attach+ }

[cxml-devel] validating without parsing?
by Cyrus Harmon 01 Mar '12

01 Mar '12

cxml and cxml-rng folks, I see that I can use a validator like so (from the examples): (cxml:parse-file "example.xml" (cxml-rng:make-validator (cxml-rng:parse-schema #p"example.rng") (cxml-dom:make-dom-builder))) But is there any way I can validate an already parsed (in-memory) XML (preferably STP) document? thanks, Cyrus

Apologies for the multiple postings. PAPER SUBMISSION DEADLINE EXTENDED European Lisp Symposium 2012, Zadar, Croatia, April 30th - May 1st, 2012 http://european-lisp-symposium.org The purpose of the European Lisp Symposium is to provide a forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp and Lisp-inspired dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, and so on. We encourage everyone interested in Lisp to participate. The main theme of the 2012 European Lisp Conference is "Interoperability: Systems, Libraries, Workflows". Lisp based and functional-languages based systems have grown a variety of solutions to become more and more integrated with the wider world of Information and Communication Technologies in current use. There are several dimensions to the scope of the solutions proposed, ranging from "embedding" of interpreters in C-based systems, to the development of abstractions levels that facilitate the expression of complex context dependent tasks, to the construction of exchange formats handling libraries, to the construction of theorem-provers for the "Semantic Web". The European Lisp Symposium 2012 solicits the submission of papers with this specific theme in mind, alongside the more traditional tracks which have appeared in the past editions. We invite submissions in the following forms: Papers: Technical papers of up to 15 pages that describe original results or explain known ideas in new and elegant ways. Demonstrations: Abstracts of up to 4 pages for demonstrations of tools, libraries, and applications. Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes.

[cxml-devel] [PATCH][CXML-STP] Fix tests to work with :invert readtable case
by Jyrki Jaakkola 22 Jan '12

22 Jan '12

Changed with-ATTRIBUTE-test to with-attribute-test so that the calling code can find the macro as they were using with-attribute-test. Signed-off-by: Jyrki Jaakkola <jjkola at email dot com>

[cxml-devel] [PATCH] Fix :invert readtable case problems
by Jyrki Jaakkola 21 Jan '12

21 Jan '12

Fixed quite many cases where symbols were in uppercase. Also fixed one case where string was used as symbol name. There was also two cases of symbols which were missing vertical bars when the other occurences used them. Changes in klacks/klacks.lisp courtesy of Hans Hübner.

[cxml-devel] [PATCH] map-node now converts non-string attributes and values to strings
by Daniel Lowe 10 Jan '12

10 Jan '12

While switching over from using xmls, I ran into a few problems with the conversion. Xmls will convert non-string attributes and values to strings, while cxml:map-node won't. Here's a patch to fix that. : Daniel : --- xml/xmls-compat.lisp | 18 ++++++++++-------- 1 files changed, 10 insertions(+), 8 deletions(-) diff --git a/xml/xmls-compat.lisp b/xml/xmls-compat.lisp index aa3d8bc..3804f8a 100644 --- a/xml/xmls-compat.lisp +++ b/xml/xmls-compat.lisp @@ -177,19 +177,21 @@ (defun map-node/qnames (handler node include-xmlns-attributes) (sax:start-document handler) (labels ((walk (node) - (when (node-ns node) - (error "serializing without :INCLUDE-NAMESPACE-URI, but node ~ + (when (node-ns node) + (error "serializing without :INCLUDE-NAMESPACE-URI, but node ~ was created with a namespace URI")) (let* ((attlist - (compute-attributes/qnames node include-xmlns-attributes)) - (qname (string-rod (node-name node))) + (compute-attributes/qnames node include-xmlns-attributes)) + (qname (string-rod (node-name node))) (lname (nth-value 1 (cxml::split-qname qname)))) (sax:start-element handler nil lname qname attlist) (dolist (child (node-children node)) (typecase child (list (walk child)) ((or string rod) - (sax:characters handler (string-rod child))))) + (sax:characters handler (string-rod child))) + (t + (sax:characters handler (string-rod (princ-to-string child)))))) (sax:end-element handler nil lname qname)))) (walk node)) (sax:end-document handler)) @@ -212,7 +214,7 @@ (string-rod lname)) :local-name (string-rod lname) :namespace-uri uri - :value (string-rod value) + :value (string-rod (princ-to-string value)) :specified-p t)) (xmlnsp (sax:make-attribute @@ -222,7 +224,7 @@ "xmlns")) :local-name (string-rod lname) :namespace-uri uri - :value (string-rod value) + :value (string-rod (princ-to-string value)) :specified-p t)))))) (node-attrs node)))) @@ -237,7 +239,7 @@ (if (or xmlnsp (not (cxml::xmlns-attr-p (string-rod name)))) (sax:make-attribute :qname (string-rod name) - :value (string-rod value) + :value (string-rod (princ-to-string value)) :specified-p t) nil))) (node-attrs node)))) -- 1.7.5.4

[cxml-devel] cxml install problem
by Noldus Reijnders 19 Dec '11

19 Dec '11

Hey all, When I try to install "cxml" through quicklisp:(ql:quickload "cxml") I get the following error:Attempt to set dispatch macro in system readtable #<readtable @ #x20107f7a>; copy readtable first. when it loads:"...\portableaserve-pre-lw6\libs\puri-1.3.1\src.fasl" Recompiling/reloading doesn't help. I tried copying the readtable, like it says in the error, but I'm not sure when/how to use copy-readtable (I'm not that experienced in Lisp (yet)), nor do I know what exactly causes the error. Is there perhaps someone that can help me? Or am I at the wrong place and should I look for puri help? Regards,Noldus PS I'm running Allegro CL.

[cxml-devel] [PATCH] A memory leak in klacks parser
by Kalyanov Dmitry 16 Nov '11

16 Nov '11

I've been trying to parse a relatively large XML file with Klacks and found what seems to be a memory leak inside Klacks parser. 1) When klacks sees the start of an element, an URI is pushed to the 'base-stack' field of 'context' structure ('klacks/element' calls 'p/sztag' which pushes the URI) but never actually removes it off the stack. 2) Similarly, klacks pushes the namespace to the 'namespace-stack' field of 'cxml-source' structure but never actually removes it off the stack ('klacks/element-2' pushes the namespace). Attached is a proposed patch that seems to fix these issues. With the patch, memory usage stays (almost) constant during parsing.
