关键是利用unicode内部编码
主要介绍了python的编码机制，unicode, utf-8, utf-16, GBK, GB2312,ISO-8859-1 等编码之间的转换。
**常见的编码转换分为以下几种情况：**
===== unicode 转换为其它编码(GBK, GB2312等) =====
例如：a为unicode编码 要转为gb2312。a.encode('gb2312')
<code python>
# -*- coding=gb2312 -*-
a = u"中文"
a_gb2312 = a.encode('gb2312')

出现这个问题是因为在编译python的时候没有把LD_LIBRARY_PATH处理好,只要在运行前指定下该变量:
export LD_LIBRARY_PATH=/your/python/lib/directory
然后在运行python就可以了.
或者在编译的时候把LD_LIBRARY_PATH放进来.

这是一种判断两棵DOM树匹配程度的方法，返回的是两棵树有相同标签节点的最大数目
def TreeMatch(A,B):
med=[0,-1,-1]
if A.tag!=B.tag:return med
m=len(A.getchildren())
n=len(B.getchildren())
maxl=max(m,n)
M=[[0 for x in range(n+1)]for y in range(m+1)]
W=[[0 for x in range(n+1)]for y in range(m+1)]

首先是安装lxml
doc.xpath()返回一个满足条件的list
# coding=gb2312
from lxml import *
import lxml.html
import urllib2
import lxml.html as H
def getjarinfo(url):
c=urllib2.urlopen(url)
f=c.read()
doc = H.document_fromstring(f)
tables=doc.xpath("//table[@id='xiazai']") ...

必须注意，这种调用由于新开一个Process,所以是异步的。
String cmd = "MIDI0TO1 " + tmp1.getAbsolutePath()
+ " f:\\out.mid";
System.out.println(cmd);
Process proc = Runtime.getRuntime().exec(cmd);
int ret = 0;
try {
ret = proc.waitFor();
} catch (Inter ...
