</feed> 

Über XML enthält eine Liste von <entry> Elemente, die einige Informationen jeder Ausführungsschritt hat (<entry></entry> Element enthält Ausführungs Info).

Angenommen, wenn alle "Eintrag" Elemente erhalten möchten, die rc aufweisen, sind = 0.

Für Ex:

<sop:status state='Finished' rc='1'/> 
<sop:status state='Finished' rc='2'/> 

Dazu verwende ich XPath-Abfrage (siehe unten), aber ich kann nichts bekommen.

/feed/entry/sop:status[@ rc!="0"] 
and 
//entry/sop:status[@ rc!="0"] 

Ist dies der richtige Weg, XML zu parsen, kann jemand dabei helfen?

Answer 1

Ihre XML hat Standard-Namespace:

xmlns="http://www.w3.org/2005/Atom" 

Beachten Sie, dass ohne Präfix Element Standard-Namespace von Vorfahren erbt implizit. Sie benötigen einen Präfix kartieren, sagen d, auf den Standard-Namespace-URI, und das Präfix Element im Standard-Namespace zu verweisen:

/d:feed/d:entry/sop:status[@rc!='0']
