[XML - DOM] getElementById

Guillaume CABANAC
Bonjour,

J'utilise DOM pour parser un fichier XMI et je souhaiterais "résoudre
les références". J'ai trouvé dans la Javadoc qu'on peut le faire grâce à la
méthode getElementById(String elementId) de la classe Document.
J'ai passé à la méthode parse le nom de l'attribut "xmi.id"... Malgré
tout cela, je n'arrive pas à obtenir l'element d'identifiant donné... Si
vous pouviez me dire à quel moment je pars dans le mur...
Mieux vaut du code que des explications hasardeuses...

Merci d'avance.

Bonjour,

J'utilise DOM pour parser un fichier XMI et je souhaiterais "résoudre
les références". J'ai trouvé dans la Javadoc qu'on peut le faire grâce à
la

méthode getElementById(String elementId) de la classe Document.
J'ai passé à la méthode parse le nom de l'attribut "xmi.id"... Malgré
tout cela, je n'arrive pas à obtenir l'element d'identifiant donné... Si
vous pouviez me dire à quel moment je pars dans le mur...
Mieux vaut du code que des explications hasardeuses...

Merci d'avance.

Bonjour,

pour que getElementById fonctionne, il faut que l'attribut sur lequel tu
fais la recherche soit déclaré de type ID dans la DTD du fichier XML. Or, tu
n'as pas de DTD attachée à ton fichier XMI. Ca ne risque donc pas de
marcher...

Bonjour,

Merci pour ta réponse. J'ai donc récupéré la DTD
(http://www.gentleware.com/support/dev/uml14di_dtd.zip) du XMI généré par
l'outil que j'utilise Poseidon. J'ai trouvé dedans :

<!ENTITY % XMI.element.att
'xmi.id ID #IMPLIED
xmi.label CDATA #IMPLIED
xmi.uuid
CDATA #IMPLIED ' >

Je peux donc en conclure que, comme prévisible, c'est xmi.id qui est de
type ID.

J'ai ensuite associé le fichier DTD (stocké localement) à mon fichier
XML, grace à l'ajout de la ligne (dans mon fichier .xmi, juste après le tag
<?xml et avant les données) : <!DOCTYPE uml14di SYSTEM
"file:C:/uml14di.dtd">

Résultat : j'arrive à résoudre les références ! J'ai entendu parler de
XPointer... Pourriez-vous m'en dire un peu plus ?

Merci encore ;)
