[xml] Probs with xmlCtxtReadFile() !!


I work with the libxml2 version 2.6.11 on an embedded linux plattform.

The configuration is:

./configure --with-minimum --with-output --with-xpath --with-xinclude --with-tree --with-xptr --with-push --with-sax1 --with-writer --with-reader --with-pattern --disable-static --with-valid --with-html --with-docbook --with-legacy

I want to use xmlCtxtReadFile to validate a xml against his dtd, but it doesn't work and I don't know why.

For tests I used the same code like on "www.xmlsoft.org/examples/parse2.c"

(so I took the right xmlParserOption).

Please take a look to the following example and possibly you could tell me

what´s wrong.

DTD - "ACK.R01.dtd":


<!ELEMENT HDR (HDR.message?, HDR.control, HDR.version,

                HDR.creation, HDR.encoding?)>


<!ELEMENT ACK (ACK.type, ACK.ack_control, ACK.note?,


XML_1 - "ACK.R01.xml":

<?xml version="1.0" encoding="UTF-8"?>











XML_2 - "ACK.R01.xml":

<?xml version="1.0" encoding="UTF-8"?>










When validating XML_1, i get  'ctxt->valid = 1'.

When validating XML_2, i get  'ctxt->valid = 0'.

Why?? They using the same dtd and in both xml-versions required elements are

missing! So with both xml versions i had to get  'ctxt->valid = 0'. (Or not?)

I also tried

xmllint --valid --noout ACK.R01.xml

from the command line.

With XML_1 I get: no error

With XML_2 I get: ACK.R01.xml:1: element HDR: validity error : Element HDR

content does not follow the DTD, expecting (HDR.message? ,

HDR.control , HDR.version , HDR.creation ,

HDR.encoding?), got ()



I tested it with several xml files. Whatever xml-file i take, i get an error only when something is wrong within the first element (in my case HRD).

Does anyone have an idea what is wrong?

I have searched

"http://www.xmlsoft.org/FAQ.html", "http://xmlsoft.org/bugs.html",

"http://www.xmlsoft.org/news.html", "http://www.xmlsoft.org/xmldtd.html",


for changes in xmlCtxtReadFile since version 2.6.11 too, but i couldn't find

any hints or infos.

thanks and best regards,
