[Python]_[使用正则表达式提取迅雷界面配置文件XLUE的图片]

场景:

1.某种情况需要提取XLUE里的图片.如果量大的话对照XLUE里的一个个copy出来很费时。

2.可以用python快速提取图片.这种速度是C++,Java不能比拟的.

文件1: test.xml

<XLUE>
<resource>
	<imagelist id="test.imagelist"  vertical="0"  splitter="1" varyblock="0" blocksize="23" image="bitmap\pup.png"/>
	<texture id="test.pup.click.image"   type="NineInOne" imagelist="test.imagelist" index="1"/>

	
	<!--Mask-->
	<texture id="texture.mask.btn" type="ThreeInOneH" image="bitmap/mask.btn.png" />
	
	<!--BkgCtrl-->
	<texture id="bkg.light.left" type="NineInOne" image="bitmap\bkg.light.left.png"/>
	<texture id="bkg.light.right" type="ThreeInOneV" image="bitmap\bkg.light.right.png"/>
</resource>
</XLUE>

文件2:test_python_re.py

#! encoding=utf-8

# 导入正则包
import re
import os
import sys
import shutil

def printBitmap(xmlPath):
	f = open(xmlPath)
	line = f.readline()
	mode = '\"[^\"]+.png\"|<!--.+-->'
	pattern = re.compile(mode) #预编译匹配规则
	
	modeDirName = "<!--(.+)-->"
	patternDirName = re.compile(modeDirName);
	#decode为unicode字符串,为了能创建中文路径.
	picDir = "face/全局/".decode("utf-8")
	try:
		os.makedirs(picDir)
	except Exception, e:
		pass
	while line:
#		print line,
		strMatch = pattern.findall(line) #查找所有匹配字符串
		size = len(strMatch)
		for i in range(0,size,1):
			one = strMatch[i]
			print one
			one = one.replace("\\","/");
			one = one.replace("\"","");
			dirMatch = patternDirName.match(one);
			try:
				if(dirMatch):
					picDir = "face/"+dirMatch.group(1)+"/" #获取分组,分组从1开始,0的话是全匹配的字符串.
					print picDir
					picDir = picDir.decode("utf-8")
					os.mkdir(picDir)
				shutil.copy(one,picDir);
			except Exception, e:
				pass
		line = f.readline()
	f.close()

if __name__=='__main__':
	printBitmap("test.xml")

输出:

---------- Run ----------
"bitmap\pup.png"
<!--Mask-->
face/Mask/
"bitmap/mask.btn.png"
<!--BkgCtrl-->
face/BkgCtrl/
"bitmap\bkg.light.left.png"
"bitmap\bkg.light.right.png"
