Hallo,
ich möchte, wie unten zu sehen, eine XML Datei auslesen. Dafür nutze ich den SAXParser und den DefaultHandler. Er liest einige der Daten aus aber nicht alle. Zum Beispiel bekomme ich nie das Feld "locked" ausgelesen, weil er nicht einmal in den Knoten reingeht, obwohl im Defaulthandler "locked" gefunden wurde. Vllt könnt ihr mir da weiterhelfen. Unten führe ich die nötigen Dateien auf.
Erzeugen des SAXParser und des Handlers
Und nun der Handler, wo er nie in den locked Teil geht.
Vielen Dank für die Hilfe
ich möchte, wie unten zu sehen, eine XML Datei auslesen. Dafür nutze ich den SAXParser und den DefaultHandler. Er liest einige der Daten aus aber nicht alle. Zum Beispiel bekomme ich nie das Feld "locked" ausgelesen, weil er nicht einmal in den Knoten reingeht, obwohl im Defaulthandler "locked" gefunden wurde. Vllt könnt ihr mir da weiterhelfen.

Code:
<time-entries type="array">
<time-entry>
<id type="integer">8295580</id>
<date-at type="date">2011-09-03</date-at>
<minutes type="integer">120</minutes>
<revenue type="float" nil="true"/>
<project-id type="integer">491108</project-id>
<locked type="boolean">true</locked>
<service-id type="integer">160608</service-id>
<user-id type="integer">39342</user-id>
<created-at type="datetime">2011-09-02T20:05:50+02:00</created-at>
<updated-at type="datetime">2011-09-03T13:21:33+02:00</updated-at>
<billable type="boolean">false</billable>
<note/>
<user-name>Pascal geldmacher</user-name>
<customer-id type="integer">137475</customer-id>
<customer-name>deltra</customer-name>
<project-name>Projekt #5</project-name>
<service-name>Support</service-name>
</time-entry>
</time-entries>
Erzeugen des SAXParser und des Handlers
Code:
InputStream is = entity.getContent();
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader reader = sp.getXMLReader();
TimeXMLHandler handler = new TimeXMLHandler();
reader.setContentHandler(handler);
reader.parse(new InputSource(is));
is.close();
Und nun der Handler, wo er nie in den locked Teil geht.
Code:
