python + lxml 解析静态网页

1, firefox 下可以使用 firepath 插件 寻找到每个属性的xpath

2,感觉xpath 非常好用，简单，适合取网页中结构化的数据

import sys
import lxml.html as HTML

file=sys.argv[1]
doc = HTML.fromstring(open(file).read())

table = doc.xpath(".//*[@id='infoTable']/tbody/tr")
for i in range(1,len(table)):
    tr = table[i]
    for tds in tr:
        td = tds.text_content().strip(" \t\r\n")
        if td != "":
            print td,"\t",
    print
