使用BeautifulSoup解析表并在文本文件中写入

Question

我需要以这种格式从文本文件(output.txt)中的表中获取数据:data1; data2; data3; data4; .....

Celkova podlahova plocha bytu; 33m; Vytah; Ano; Nadzemne podlazie; Prizemne podlazie; .....; Forma vlastnictva; Osobne

全部在" 一行 "中,分隔符为" ; "(稍后在csv文件中导出).

我是初学者..帮助,谢谢.

from BeautifulSoup import BeautifulSoup
import urllib2
import codecs

response = urllib2.urlopen('http://www.reality.sk/zakazka/0747-003578/predaj/1-izb-byt/kosice-mestska-cast-sever-sladkovicova-kosice-sever/art-real-1-izb-byt-sladkovicova-ul-kosice-sever')
html = response.read()
soup = BeautifulSoup(html)

tabulka = soup.find("table", {"class" : "detail-char"})

for row in tabulka.findAll('tr'):
    col = row.findAll('td')
    prvy = col[0].string.strip()
    druhy = col[1].string.strip()
    record = ([prvy], [druhy])

fl = codecs.open('output.txt', 'wb', 'utf8')
for rec in record:
    line = ''
    for val in rec:
        line += val + u';'
    fl.write(line + u'\r\n')
fl.close()

您在阅读时没有保留每条记录.试试这个,将记录存储在records:

from BeautifulSoup import BeautifulSoup
import urllib2
import codecs

response = urllib2.urlopen('http://www.reality.sk/zakazka/0747-003578/predaj/1-izb-byt/kosice-mestska-cast-sever-sladkovicova-kosice-sever/art-real-1-izb-byt-sladkovicova-ul-kosice-sever')
html = response.read()
soup = BeautifulSoup(html)

tabulka = soup.find("table", {"class" : "detail-char"})

records = [] # store all of the records in this list
for row in tabulka.findAll('tr'):
    col = row.findAll('td')
    prvy = col[0].string.strip()
    druhy = col[1].string.strip()
    record = '%s;%s' % (prvy, druhy) # store the record with a ';' between prvy and druhy
    records.append(record)

fl = codecs.open('output.txt', 'wb', 'utf8')
line = ';'.join(records)
fl.write(line + u'\r\n')
fl.close()

这可以清理得更多,但我认为这是你想要的.
