XML parsing bug?

Oleg Parashchenko — 2011-08-26T12:28:44

Hello,

using the "ssax-sxml-gambit-060529.tgz", parsing the XML document

<p><b>so,</b> <b>so</b> and <b>so</b></p>

I get

(*TOP* (p
  (b "so,")
  (b "so")
  " and "
  (b "so")))

The space between the first "b"-tags is lost. Right now I can't check
if the latest version from the sorceforge repository produces the same
error, but I'm afraid yes, why not. Can you reproduce the bug? If yes,
is there a chance that the bug would be fixed?

how to unwrap a tag in pre-post-order

Oleg Parashchenko — 2011-08-17T11:47:57

Hello,

I try to "unwrap" an XML tag: delete the tag, but retain the subtrees.
For example, the source document:

<chapter>
  <proxy><section></section></proxy>
  <proxy><section></section></proxy>
</chapter>

after unwrapping the tag "proxy" gives:

<chapter>
  <section/>
  <section/>
</chapter>

A first attempt with SXSLT:

(define doc '(*TOP* (chapter (proxy (section)) (proxy (section)))))
(define unwrapped (pre-post-order doc `(
  (*default* . ,(lambda args args))
  (proxy     . ,(lambda (tag . kids) kids))
  )))
(display unwrapped)(newline)

The result is:

(*TOP* (chapter ((section)) ((section))))

But I want:

(*TOP* (chapter (section) (section)))

Any trick to get the desired result?

The idea is to apply several "pre-post-order" in sequence, and mix them
with sxpath expressions. But right now the result of a transformation is
not SXML anymore. Any suggestions are welcome.

Hello all! 

I am trying to learn SXML and attempting to follow to follow a tutorial at the following URL:

http://modis.ispras.ru/Lizorkin/sxml-tutorial.html

Right away I am receiving an error on example 1 hindering my progress:

here's the code (In Modular language and using PTL scheme 4.2.3 plus the latest version of SXML)



#lang scheme

(require (planet lizorkin/sxml:2:1/sxml))

(sxml:document "http://modis.ispras.ru/Lizorkin/XML/poem.xml")




The error i receive is as Follows

XLink API error: resource doesn't exist: http://modis.ispras.ru/Lizorkin/XML/poem.xml
#f


Could I be following old syntax from this website? The SXML source code (http://planet.plt-scheme.org/package-source/lizorkin/sxml.plt/2/1/xpath-context_xlink.ss) states 
"(define (sxml:document req-uri . namespace-prefix-assig)

and "NAMESPACE-PREFIX-ASSIG is an optional argument"


any help would be greatly appreciated,

Thanks!
Dan
