Re: [xwiki-users] Selective space export

Hi, 

That is not really what I want. My problem is that I have an xwiki 1.7.14 and I 
wanto to move to a 2.0milestone 2 in another machine. I get a lot of corrupted 
xar files (cannot open them with 7zip) because of java memory heap exception 
(even if they are spaces of only one page!). So I need a different way of 
exporting the data, because if I have 40 spaces, 10 xar files are corrupted. 
Even, I wrote my own snippet to get the spaces exported selectively, but still 
getting corrupted xar files. So, ¿is it posible to backup the database and 
import it in the new installation?


BTW, I attach the code I wrote for selective space exporting (no optimiced, no 
commented).


--------------------
#set($spaces = $xwiki.spaces)
There are $spaces.size() spaces
#set($base ="?format=xar&history=false")
#set( $url=$doc.getURL("export")+$base)
#set( $url=$url.toString.replace("/view/","/export/"))




<table><tr><td>
<form name="a_form">
<textarea type="text" id="a_tbox" name="a_tbox" value="" cols="30" rows="30"> 
</textarea>

<input id="b_tbox" name="textarea" ></input>

  <a id="the_link" href=" "> 
  Export 
  </a>
</form>

</td><td>


<table> 








#foreach($space in $spaces)

<tr><td>  
#set($contador=0)

  #set($parametros = "&name="+$space)

  #foreach ($item in $xwiki.getSpaceDocsName($space))
     #set($contador=$contador +1)
     #set($parametros = $parametros + "&pages=" + $space + "." + $item )


#end



#set( $parametros=$parametro.toString.replace("/view/","/export/"))

<a href="$url$parametros">Export $space con $contador paginas</a>
</td><td>
<a onclick="javascript:writeit('Añadido $space 
\n','a_tbox');appendit('$parametros','b_tbox','the_link')" >Añadir</a>
</td>
<td>
#set($rdoc = $xwiki.getDocument($space).getTranslatedDocument())
#set($view_url=$rdoc.getURL('view'))

<a href="$view_url/Webhome">Ir</a>
</td>

</tr>

#end

</table>

</td></tr></table>


<script type="text/javascript">
function writeit(txt,cosa)
{

var tbox = document.getElementById(cosa);
if (tbox)
{
tbox.value =tbox.value+ txt;
}
}

function appendit(txt,cosa,link)
{

var tbox = document.getElementById(cosa);
var linkea = document.getElementById(link);
if (tbox)
{
tbox.value = tbox.value+txt;
linkea.href="$url" +tbox.value;
}
}
</script>
--------------------
Thanks

Francisco

Hallo Francisco,

I recently exported my entire database for the first time. I noticed that when 
you import the XAR file there are checkboxes that permit you to leave out what 
you want. Is that what you need? Xwiki permits choosing which spaces to import, 
but the choice is on the import side not the export side. To export the entire 
DB you need to have Admin rights, though.

Best regards,

Betreff: [xwiki-users] Selective space export

Hello everybody.

 

 

Because of a java memory problem when exporting my wiki, I want to do selective 
space exports. The problem is that there is no easy snippet to do it. I found 
some code to export one space, and would be great to hace something with 
chekboxes or similiar to quickly select wich space to export. I am not good at 
the scripting language yet, so some help would be great.

 

 

I attach the code for one space exporting

 

#if(!$request.space)

  #set($space = "All")

#else

  #set($space = $request.space)

#end

#set($spacesText = {})

#set($spaces = $xwiki.spaces)

#set($ok = $spacesText.put("All","All"))

#foreach($space in $spaces)

  #set($ok = $spacesText.put($space,$space))

#end

 

#macro(spaceoption $space $selectspace $spacesText)

  <option value="$spacesText.get($space)" #if($selectspace == 
$spacesText.get($space))selected="selected"#end>$space</option>

#end

 

#macro(spaceselect $selectspace $spaces $spacesText)

  <select name="space">

    #spaceoption("All" $selectspace $spacesText)

    #foreach($space in $spaces)

      #spaceoption($space $selectspace $spacesText)

    #end

  </select>

#end

 

<form action="">

  {pre}

    <div class="centered">

      Space #spaceselect($space $spaces $spacesText) <input type="submit" 
value="Ver"/>

    </div>

  {/pre}

</form>

 

#if ($request.space)

    1.1 List of docs that will be Exported

 

  #set($parametros = "?format=xar&history=false&name="+$space)

 

  #foreach ($item in $xwiki.getSpaceDocsName($request.space))

     * $item

     #set( $parametros = $parametros + "&pages=" + $space + "." + $item )

  #end

#set( $parametros=$doc.getURL("export")+$parametros )

#set( $parametros=$parametro.toString.replace("/view/","/export/"))

<a href="$parametros">Exportar</a>

#end
