jQuery Grid Plugin - jqGrid

Hi,

Not found/understood in the docs or forum ...

The XML looks like :
...
<details>

<detail dispo="1" id="192390" pic="loisir_ae.gif">
<intitule>1 YAKAREVERZZZ</intitule>
<intituleGb/>
<intituleDe/>
<intituleNl/>

<intituleEs/>
<ville>
<inseeVille>17300</inseeVille>
<intituleVille>LA ROCHELLE</intituleVille>
</ville>
<ouvertureAnnee value="0"/>
<periodesOuvertures>
<periodeOuverture>
<periodeOuvertureDebut>2008-01-01</periodeOuvertureDebut>
<periodeOuvertureFin>2008-12-31</periodeOuvertureFin>
</periodeOuverture>
</periodesOuvertures>
<periodesOuverturesOld/>

<dateMAJ>20081124014609</dateMAJ>
<dateValidite>
<dateValiditeDebut>2008-01-04</dateValiditeDebut>
<dateValiditeFin>2008-12-31</dateValiditeFin>
</dateValidite>

</detail>
...
</details>

My problem is with the <ouvertureAnnee value="0"/> tag ...
How to get the "value" parameter ?

in my xmlReader :
root:'details',
row:'detail',
repeatitems:false

If I set repeatitems to true, no data are displayed
