retour <options> liste de <select> boîte avec python (mécaniser/twill)

Question

Si je devais obtenir quelque chose comme ça avec showforms(), comment pourrais-je obtenir les Value s de la boîte d'entrée SOME_CODE?

Form name=ttform (#2) 
## ## __Name__________________ __Type___ __ID________ __Value__________________ 
1  NUMBER     select (None)  ['0'] of ['0', '10', '2', '3', '4', ... 
2  SOMEYEAR     select (None)  ['201009'] of ['201009', '201007'] 
3  SOME_CODE    select (None)  ['AR%'] of ['AR%', 'AR01', 'AR02', ' ... 
4  OTHR_CODE    select (None)  ['%'] of ['%', 'AAEC', 'ACIS', 'AEE' ... 

Merci!

lors du débogage des formes que j'utilise les éléments suivants:

def getFormControlByLabel(self, form, label): 
    for control in form.controls: 
    self.log.debug("checking control %s dict = %s" % (control,control.__dict__)) 
    if 'items' in control.__dict__: 
     self.log.debug("control %s has items field len %d" % (control, len(control.__dict__['items']))) 
     if len(control.items) > 0: 
      if 'label' in control.items[0].attrs: 
       self.log.debug("control %s has label %s" % (control, control.items[0].attrs['label'])) 
       if control.items[0].attrs['label'] == label: 
       self.log.debug("control %s has label %s" % (control,label)) 
       return control 
    for control in form.controls: 
    try: 
     if control.items[0].attrs['label'] == label: 
      # y.items[0].attrs['label'] 
      self.log.debug("control %s has matching label %s" % (control,label)) 
      return control 
     else: 
      self.log.debug("control %s has label %s" % (control,control.items[0].attrs['label'])) 
    except: 
     pass

Cela fait ce que vous voulez. Testé sur un site que j'ai trouvé avec le type de contrôle de sélection que vous avez ci-dessus:

>>> import twill.commands 
>>> import BeautifulSoup 
>>> import re 
>>> 
>>> a=twill.commands 
>>> a.config("readonly_controls_writeable", 1) 
>>> b = a.get_browser() 
>>> b.set_agent_string("Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14")
