regex not working - options field too short

[m1ch]

The saveing of data source HTML grapper is not possible with the following combination. I tested the regex with no issues, but I cant save it. No error or warning given.

I suspect that the regex contains something creating the issue.

Datasource:
https://www.pollenwarndienst.at/prognose/3-tages-prognose.html?tx_scload_load%5Bzip%5D=8020

Regex:
/(<h3 class="polltitle">)(?<dimension>Erle)(\s.*\n){9,15}(.*<span class="invisible">\s*)(?<value>(Keine Belastung|niedrig|mittel|hoch|sehr hoch))(<\/span>)/

Result from https://pt.functions-online.com/preg_match_all.html:

  0 => 
  array (
    0 => '<h3 class="polltitle">Erle (Alnus)</h3>

                                        <div class="date">Dienstag, 17. März</div>
                                        

<div class="contaminationbar">
    
        <div class="number number_2">2</div>
        <div class="bar bar_2"></div>
    

    
        
        
        <span class="invisible"> mittel</span>',
  ),
  1 => 
  array (
    0 => '<h3 class="polltitle">',
  ),
  'dimension' => 
  array (
    0 => 'Erle',
  ),
  2 => 
  array (
    0 => 'Erle',
  ),
  3 => 
  array (
    0 => '        
',
  ),
  4 => 
  array (
    0 => '        <span class="invisible"> ',
  ),
  'value' => 
  array (
    0 => 'mittel',
  ),
  5 => 
  array (
    0 => 'mittel',
  ),
  6 => 
  array (
    0 => 'mittel',
  ),
  7 => 
  array (
    0 => '</span>',
  ),
)

Thank you for posting a real world example

Hello,

2 things: first, there is an issue with DA. The field for the data load parameters is too short in the database (255). I need to fix this.

even with the fix locally, the debug of the pregmatch is still strange - even so it works in the online simulator

{\"0\":[],\"1\":[],\"dimension\":[],\"2\":[],\"3\":[],\"4\":[],\"value\":[],\"5\":[],\"6\":[],\"7\":[]}

I will see what I can find

Hello @m1ch
there seems to be an issue with the line brakes (possibly during php capturing?). when I modify the code a little, it works.

/(<h3 class="polltitle">)(?<dimension>Erle)([\S\s]+)(<span class="invisible">\s*)(?<value>(Keine Belastung|niedrig|mittel|hoch|sehr hoch))(<\/span>)/

BUT:
your value is a text. DA expects a value here.
Can you please let me know how you want to use this information in a report?

• a table with the current values?
• a table with the history?
• a chart?

working with the <div class="number number_2">2</div> could bring a value.
let me know what you want to achieve
