HTTPMOD - Regex-Ausdruck für WeatherLink Website

Stargazer · 09 Juni 2017, 12:46:58

Hallo,

ach klar. Vergessen !

Das Regex heißt natürlich : (?s)Wind Direction.+?>([\d\.]+)

Trotzdem schon einmal vielen Dank für deine Hilfe !

Hast Du den Vorschlag von amenomade schon getestet?

Code Auswählen

(?s)Wind Direction.*?data\">([NWES]+)
(?s)Wind Direction.*?data\">.*?([\d]+)

Hi,

Jepp. Gerade den zweiten getestet. Die laufen beide Perfekt !!
Ein fettes DANKESCHÖN! nochmal dafür.

Jetzt muss ich das für die Regenmenge noch korrigieren.

Da setze ich derzeit folgendes Regex ein:

(?s)Rain.+?>([\d\.]+)

Der Code-Teil sieht folgendermaßen aus:

Code Auswählen

 <tr><td colspan="6"><hr class="ThinLine"></td></tr> <tr><td colspan="6"><img src="/images/spacer.gif" width="10" height="11" border="0" alt=""></td></tr> <tr> <td width="190" class="summary_header_label">Rain</td> <td width="170" class="summary_header">Rate</td> <td width="100" class="summary_header">Day</td> <td width="100" class="summary_header">Storm</td> <td width="100" class="summary_header">Month</td> <td width="100" class="summary_header">Year</td> </tr> <tr><td colspan="6"><hr class="ThinLine"></td></tr> <tr> <td width="190" class="summary_data">Rain</td> <td width="170" class="summary_data">0.0mm/Hour</td> <td width="100" class="summary_data">5.6mm</td> <td width="100" class="summary_data">5.6mm</td> <td width="100" class="summary_data">14.2mm</td> <td width="100" class="summary_data">203.4mm</td> </tr> <tr> <td width="190" class="summary_data">Last Hour Rain</td> <td width="170" class="summary_data">0.4mm</td> <td width="100" class="summary_data">&nbsp;</td> <td width="100" class="summary_data">&nbsp;</td> <td width="100"

Wenn ich das Regex von oben nehme, so bekomme ich immer den Wert von "mm/hour" angezeigt. Leider noch nicht die Tagesregenmenge. Da werde ich nochmal nachforschen. Müsste jetzt ja gehen...

.

Und wo ist die Tagesregenmenge?

amenomade · 09 Juni 2017, 16:41:05

Wenn das die erste 5.6 ist, dann überleg wie folgendes (ich will nicht unbedingt zukünftig alle deine Regex selbst schreiben

) :
- match Rain
- dann match so wenig wie möglich Zeichen bis
- match Hour
- dann match so wenig wie möglich Zeichen bis match > dann
- capturing group with digit oder punkt

Die rechte Spalte in regex101 detailliert das ganze.

amenomade · 09 Juni 2017, 16:44:20

Wenn "mm/Hour" nur einmal in der ganze Seite kommt, noch einfacher:
- match mm/Hour
- dann match so wenig wie möglich Zeichen bis match > dann
- capturing group with digits oder punkt

Hi amenomade !

das stimmt schon. Ich möchte da auch selber gerne bei und lernen. Darum versuche ich das derzeit. Nur habe ich ja das Problem, dass ich mit dem jetzigen Auswerten doch etwas zu hoch für mein Wissen bin.
Das Kernproblem liegt eigentlich darin, dass sich zig Zeilen des Quelltextes gleichen.

Siehe hier:

Code Auswählen

</tr>
	<tr><td colspan="6"><hr class="ThinLine"></td></tr>
	<tr>
		<td width="190" class="summary_data">Rain</td>
		<td width="170" class="summary_data">0.8mm/Hour</td>
		<td width="100" class="summary_data">8.6mm</td>
		<td width="100" class="summary_data">8.6mm</td>
		<td width="100" class="summary_data">17.2mm</td>
		<td width="100" class="summary_data">206.4mm</td>
	</tr>
	<tr>
		<td width="190" class="summary_data">Last Hour Rain</td>
		<td width="170" class="summary_data">3.0mm</td>
		<td width="100" class="summary_data">&nbsp;</td>
		<td width="100" class="summary_data">&nbsp;</td>
		<td width="100" class="summary_data">&nbsp;</td>
		<td width="100" class="summary_data">&nbsp;</td>
	</tr>
	<tr><td colspan="6"><hr class="ThinLine"></td></tr>

Das derzeitige Regex ist:

<td width="100" class="summary_data">([0-9.]*)

Hätte das "...width=100" eine andere Nummer, z.B., könnte ich das sofort alleine lösen.
Da bin ich derzeit noch dran. Schön wäre ja noch, wenn es mit abzählen der Zeichen im Regex funktionieren
würde. So wie auf Seite 1 dieses Threads beschrieben.

Viele Grüße und besten Dank

André

PS.: Man müsste versuchen, die Zeilen vom einfachen >Rain< bis zu dem Wert mit in die Regex einzufügen.

amenomade · 09 Juni 2017, 20:05:44

Zitat<td width="100" class="summary_data">

ist aber weit von eindeutig!

Such dir eindeutige Kriterien.

Stargazer · 09 Juni 2017, 22:37:37

Eben,

und da bin ich derzeit noch für mich am Knobeln... .

Wenn das die erste 5.6 ist, dann überleg wie folgendes (ich will nicht unbedingt zukünftig alle deine Regex selbst schreiben ) :
- match Rain

Code Auswählen

(?s)Rain

Zitat von: amenomade am 09 Juni 2017, 16:41:05
- dann match so wenig wie möglich Zeichen bis

Code Auswählen

.+?

Zitat von: amenomade am 09 Juni 2017, 16:41:05
- match Hour

Code Auswählen

Hour

Zitat von: amenomade am 09 Juni 2017, 16:41:05
- dann match so wenig wie möglich Zeichen bis

Code Auswählen

.+?

Zitat von: amenomade am 09 Juni 2017, 16:41:05
match > dann

Code Auswählen

>

Zitat von: amenomade am 09 Juni 2017, 16:41:05
- capturing group with digit oder punkt

Code Auswählen

([\d.]+)

gibt zusammen:

Code Auswählen

(?s)Rain.+?Hour.+?>([\d.]+)

Zitat von: amenomade am 09 Juni 2017, 16:44:20
Wenn "mm/Hour" nur einmal in der ganze Seite kommt, noch einfacher:
- match mm/Hour
- dann match so wenig wie möglich Zeichen bis match > dann
- capturing group with digits oder punkt

Code Auswählen

(?s)mm\/Hour.+?data">([\d.]+)

Viele Grüße

Hallo Manfred,

DANKE ! Du hast mir erstmal den Kopf gewaschen !
Jetzt hat es "Klick" gemacht.

Ich nehme nun für die Monatsregenmenge folgenden Ausdruck:

(?s)mm\/Hour.+?data">([\d.][\d]+..)

Und für die Jahresregenmenge dann natürlich:

(?s)mm\/Hour.+?data">([\d.][\d][\d]+..)

Vielen Dank und beste Grüße

André

PS.: Hatte heute erst wieder Zeit, an dem Projekt zu arbeiten.

Hallo André,

Code Auswählen

(?s)mm\/Hour.+?data">([\d.][\d]+..)
funktioniert leider nicht mehr für den Monat sobald es an einem Tag 10.0mm oder mehr regnet.

Code Auswählen

Day:  (?s)mm\/Hour.+?">([\d.]+)
Storm:(?s)mm\/Hour.+?">.+?">([\d.]+)
Month:(?s)mm\/Hour.+?">.+?">.+?">([\d.]+)
Year: (?s)mm\/Hour.+?">.+?">.+?">.+?">([\d.]+)

Das geht sicher auch einfacher, sollte aber erstmal zuverlässiger funktionieren und ist so hoffentlich auch ohne Erklärung verständlich.

Viele Grüße
Manfred
