Problem mit XML Datei lesen

fschaef

Hallo und Guten Abend an Alle,
ich möchte eine Datei (XML) parsen. Dazu habe ich mir die xmldom besorgt.
Wenn ich jetzt die Anzahl der Nodes ausgeben lassen will, erhalte ich folgende Fehlermeldung:

Ich bin mir aber hundertprozentig sicher, daß es hunderte von Einträgen für "entry" gibt.

Auszug aus der XML:

Hier mein Script:

[autoit]

Global $debugging = True

[/autoit][autoit][/autoit][autoit]

$rc = _XMLFileOpen(@ScriptDir & "\test.xml")
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $rc = ' & $rc & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
if $rc = 1 Then
$iEntryCnt = _XMLGetNodeCount("/feed/entry", "", $NODE_ELEMENT)
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $rc = ' & $iEntryCnt & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
EndIf

[/autoit]

Vielen Dank schon mal für Eure Hilfe.

Nächstes mal bitte folgende Dinge beachten:

- autoit Quellcode Tag verwenden -->
- sonstigen code der nicht autoit ist (Consolen Fehlermeldungen / xml Auszug) mit dem code Tag posten -->
- längere code Passagen zusätzlich in Spoiler packen -->
- Fremd includes wie die "_XMLDomWrapper.au3" entweder verlinken oder als Dateianhang posten

Nun zu deinem Fehler:

Zitat von Funktionsbeschreibung _XMLGetNodeCount

Parameter(s): $path xml tree path from root node (root/child/child..)

Demnach könnte diese Zeile falsch sein, hab es aber nicht getestet:

[autoit]

$iEntryCnt = _XMLGetNodeCount("/feed/entry", "", $NODE_ELEMENT) ; falsch?
$iEntryCnt = _XMLGetNodeCount("feed/entry", "", $NODE_ELEMENT) ; richtig?

[/autoit]

Ok, danke schön. Ich werde Deine Hinweise beherzigen.
