python - Access element using xpath? -

-

i links of elements in first column in page (http://en.wikipedia.org/wiki/list_of_school_districts_in_alabama).

i comfortable using beautifulsoup, seems less well-suited task (i've been trying access first child of contents of each tr hasn't been working well).

the xpaths follow regular pattern, row number updating each new row in following expression:

xpath = '//*[@id="mw-content-text"]/table[1]/tbody/tr[' + str(counter) + ']/td[1]/a'

would me posting means of iterating through rows links?

i thinking along these lines:

urls = []  while counter < 100:      urls.append(get xpath('//*[@id="mw-content-text"]/table[1]/tbody/tr[' + str(counter) + ']/td[1]/a'))      counter += 1

thanks!

here's example on how can of links first column:

from lxml import etree import requests  url = "http://en.wikipedia.org/wiki/list_of_school_districts_in_alabama" response = requests.get(url)  parser = etree.htmlparser() tree = etree.fromstring(response.text, parser)  row in tree.xpath('//*[@id="mw-content-text"]/table[1]/tr'):     links = row.xpath('./td[1]/a')     if links:         link = links[0]         print link.text, link.attrib.get('href')

note, that, tbody appended browser - lxml won't see tag (just skip in xpath).

hope helps.

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
