Hallo zusammen,
ich hatte ja in einem anderen Thread beschrieben, wie ich aus meinem HTTPMOD-Modul die Wetterdaten unserer Wetterstation auszulesen.
Im speziellen geht es um den Windmesser. Dieser gibt mit: (?s)>Wind</td>(.*?)<\/td> folgendes aus:
1,1 m/s from 352° (N)
Die Rohdaten sehen so aus: <tr> <td class="stats_label">Wind</td> <td class="stats_data">1,7 m/s from 341° (NNW)</td> </tr>
Das läuft super, obwohl regex101.com sagt....nö...würde wohl nicht funktionieren. Es läuft aber perfekt.
Doch nun würde ich gerne nur den ersten Wert, sprich die 1,7, extrahieren. Da habe ich schon so manche Zeile in regex101.com versucht. Doch so richtig fruchtet es noch nicht.
Wenn es nur um diese eine Zeile ginge, würde (?s)a">(.*?)\s funktionieren. Doch leider haben alle Wetterparameter, die ausgelesen werden, die gleichen Zeichen, bis halt auf Parametername (>Wind<,>Barometer<..etc) und dessen Messwert.
Hier mal ein Auszug der Rohdaten:

Welchen Term brauche ich da, damit ich nur den Zahlenwert habe ?
Viele Grüße und vielen Dank

(?s)>Wind<\/td>.*?>([\d,]*)regex101 gibt mir bei deinen Rohdaten für den obigen RegEx genau die "1.7" zurück...
lg, Stefan
Edit: Wenn du mehrere Werte willst (also zB Baro oder Wind) nimm einfach
(?s)>(Wind|Barometer)<\/td>.*?>([\d,]*)das gibt dann ein:
ZitatMATCH 1
1. [1607-1616] `Barometer`
2. [1645-1651] `1022,8`
MATCH 2
1. [1800-1804] `Wind`
2. [1833-1836] `1,7`
Hi Stefan,
da hätte ich noch länger dran feilen müssen, um den Term zu bekommen. Mit den eckigen Klammern bin ich zwar auch schon angefangen, aber der Rest hätte noch gedauert.
Vielen Dank für die schnelle Hilfe !
