[NizarK]

J'ai un problème que je n'arrive ni à cerner ni à résoudre :

1 - Je réalise plusieurs manipulations sur un fichier XML dans un programme Java avec dom4j.

2 - Je sauvegarde ce fichier XML sur demande de l'utilisateur comme suit :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
 
FileWriter fw = new FileWriter(file.getAbsoluteFile());
fw.write(doc.asXML());
fw.flush();
fw.close();

3 - Lorsque je veux charger le fichier dans un document dom4j je fais ceci :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7

10
 
FileReader fr = new FileReader(file);
char[] c = new char[new Long(file.length()).intValue()];
fr.read(c);
String xml_conf = String.valueOf(c);
fr.close();
SAXReader xmlReader = new SAXReader();
try{
InputStream IS = new java.io.ByteArrayInputStream(xml_conf.getBytes("UTF-8"));
xmldoc = xmlReader.read(IS);

Tou va bien si le document XML ne contient aucun accent ( ou autre caractère spécial )
mais par exemple j' ajoute un 'é' :

Merci d'avance pour toute aide

[tchize_]

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
FileReader fr = new FileReader(file);
char[] c = new char[new Long(file.length()).intValue()];
fr.read(c);
String xml_conf = String.valueOf(c);
InputStream IS = new java.io.ByteArrayInputStream(xml_conf.getBytes("UTF-8"));

Ca fait un peu fouille inutile tout çà. Pourquoi tu ne fais pas simplement

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

is = new FileInputStream(file);

?

De plus, je serais toi, je préciserais toujours l'encodage quand j'utilise des fichiers xml:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
Writer fw = new OutputStreamWriter(new FileOutputStream(file),"UTF-8");
...
xmlReader.read(new InputStreamReader(new FileInputStream(file),"UTF-8");

[NizarK]

Merci à dieu puis à toi .
Je n'ai qu'une chose à dire ...
