assuming you are running linux you need to install the php-xml package or otherwise activate xml support in you php

It would be useful to detect that required dependencies are not available and provide the user with a friendly message. From memory we do this in scenarios like Twitter integration when curl extension is not available.

You are right, I am running with Linux (Fedora).

As proposed, I installed "php-xml", and this solves my issue. (do not forget to restart httpd).

But I am still unable to imoprt any XML files. I suppose this is due to the XML structure needed.
I tried to follow the procedure of the (old?) Import/export plugins http://bugtracker.morinie.fr/mantis/dokuwiki/doku.php?id=mantis:13:importing_issue_s#importing_issue_s :

I also tried some modified version of the XML export file, but without any success. Is there a procedure, or examples ? (google seems not to be my friend onto this topic)

@giallu, do we have some documentation on the import/export XML plugin?

Same situation here. Any documentation on XML import would be much appreciated.

Wether doc is available or not (a) sample of "working" XML file(s) would be very helpful as a starting point. An example of XML for custom fields would be great.

a sample of working XML file could be obtained by exporting issues via XmlImportExport plugin.
All fields can't be provided but the essentiels work well.

here a sample of working XML file :
<?xml version="1.0" encoding="utf-8" ?>

I had a vanilla install and applied some of the patches available for resolved issues in 1.2.0rc2.

using the above xml i still received the following error

Database query failed. Error received from database was 0001366: Incorrect integer value: '

( project_id,reporter_id, handler_id,duplicate_id,

last_updated,eta, bug_text_id,

)

          VALUES
            ( ?,?,?,?,
              ?,?,?,?,
              ?,?,?,?,

              ?,?,?,?,
              ?,?,?,?,
              ?,?,?,?).

i then edited the xml to have a value for profile_id as

<profile_id>0</profile_id>

and then i get

500 -内部サーバー エラーです。
検索中のリソースに問題が発生したため、表示することができません。

edit: sorry i'm running a japanese localized version...
error is
500- internal server error
There was a problem while searching for a resource, and can:t be displayed.

Same ERROR here, exported XML first, then tried to import this. No luck.

A like to update documentation, but there is no "official" starting point for "import" that I could find. Only http://www.mantisbt.org/wiki/doku.php/mantisbt:importexport

Being persistent I searche on and on, and found some links. Maybe this helps
http://bugtracker.morinie.fr/mantis/dokuwiki/doku.php?id=mantis:13:importing_issue_s

and this

http://bugtracker.morinie.fr/mantis/dokuwiki/doku.php?id=mantis:13:xml_format_and_mantis

I got some success but import does not(yet) show up.

Importing file, please wait... Done
Processing cross-references for 0 issues... Done

Well, looking into the source now.

Mantis Import/Export is a plug-in, File this defect in http://bugtracker.morinie.fr/ is probably better. But since it is included into the default 1.2.0RC package, thing get unclear.

Can xml export work with greek encoding??? like
αυτο είναι ένα τεστ

Questions are better asked on forum, this is a defect tracker. But yes, I see no reason export cannot handle a character set e.g. UTF-8 already used in your instance of the defect tracker webapp.

For those like me who have trouble finding the linux package for SUSE, it is called php5-xmlwriter.

As suggested by vboctor in 0011029:0023160, added a check in plugin's install() method to display an error message in case XMLReader class is not available

The constant ERROR_PLUGIN_INSTALL_FAILED is not defined in master-1.2.x

Thanks Roland, sorry about that... I tested in master and omitted to do the same in 1.2.x.

I backported one additional commit from giallu which defines the constant and related error message; that should do the trick.

Marking as 'acknowledged' not resolved/closed to track that change gets ported to master-2.0.x branch
