[JDOM] Problème de transformation XML

Problème de transformation XML

Bonjour tous le monde,

j'ai un petit soucis que je ne comprends pas avec ce bout de code :
Code:

1 2 3 4 5 6 7 8 9 10 11 JDOMResult documentJDOMSortie = new JDOMResult(); Document resultat = null; SAXBuilder sxb = new SAXBuilder(); Document doc = sxb.build(new File(TBXFileName)); TransformerFactory factory = TransformerFactory.newInstance(); Transformer transformer = factory.newTransformer(new StreamSource("TBXtoGraphML.xsl")); transformer.transform(new org.jdom.transform.JDOMSource(doc), documentJDOMSortie); resultat = documentJDOMSortie.getDocument(); XMLOutputter outputter = new XMLOutputter(Format.getPrettyFormat()); outputter.output(resultat, new FileOutputStream("result.graphml"));
quand j'exécute mon fichier, une java.lang.NullPointerException se déclenche.
et en debugant, j'ai remarqué que la source du problème vienne de cette ligne :
Code:

1 2 transformer.transform(new org.jdom.transform.JDOMSource(doc), documentJDOMSortie);
malgré que le "TBXtoGraphML.xsl" marche très bien sur le Terminal

Bonjour,

Je vous conseille d'écrire ceci :

Code:

1
2
3
4
5
6
7
8
9
10
11
JDOMResult documentJDOMSortie = new JDOMResult();
Document resultat = null;
SAXBuilder sxb = new SAXBuilder();
Document doc = sxb.build(new File(TBXFileName));
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource("TBXtoGraphML.xsl"));
JDOMSource jDOMSource = new org.jdom.transform.JDOMSource(doc);
transformer.transform(jDOMSource, documentJDOMSortie);
resultat = documentJDOMSortie.getDocument();
XMLOutputter outputter = new XMLOutputter(Format.getPrettyFormat());
outputter.output(resultat, new FileOutputStream("result.graphml"));

Et de debugger, n'est-ce pas la ligne

Code:

JDOMSource jDOMSource = new org.jdom.transform.JDOMSource(doc);

qui plante ?

Merci de m'avoir répondre si vite,

mais le problème est toujours le même,
c'est :
Code:

1 2 transformer.transform(jDOMSource, documentJDOMSortie);
qui plante :(

je trouve ça vraiment bizarre

Et que valent les paramètres jDOMSource et documentJDOMSortie ?

pour JDOMSource : #779
avec :
xmlReader = null
resolver = null
...

pour documentJDOMSortie : # 753
avec :
result = null
queried = false
factory = null
...

j'arrive pas à comprendre pour quoi tous ces attributs valent "null"

Avez-vous lu cette page :
http://java.developpez.com/faq/xml/?page=xslt

Il doit s'y trouver des éléments intéressants ...

oui c'est déjà fait

en tout cas, if faut que j'aille maintenant, je m'en occuperais demain
merci pour votre aide

Ce serait plus simple avec la stacktrace complète plutôt qu'avec des "le nom de l'exception c'est ça" et des "quand je débug je trouve que c'est à cette ligne" -_-° .

Et puis, quitte à faire du JDOM, ce serait plus simple avec XSLTransformer.

avec la StackTrace j'ai eu

Bon les gars, ça y est j'ai trouvé une solution
j'ai fait

Code:

1
2
3
4
5
6
 
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(new File("TBXtoGraphML.xsl")));
StreamSource source = new StreamSource(new File(TBXFileName));
StreamResult result = new javax.xml.transform.stream.StreamResult( new FileOutputStream("result.graphml"));
transformer.transform(source, result);

et elle marche nickel

merci pour vos aides
