今天周末,正好昨天对python的xml处理稍微了解了下,所以就拿出前几天申请的一个百度map的key,来处理下返回的xml文件,还好对着别人的做法,依葫芦画瓢,搞出来了.感觉效率不怎么高,估计是处理的方法有问题.凑合用了.
#!/usr/bin/python #encoding=utf8 import urllib,sys,xml.dom.minidom from xml.dom.minidom import Node def baidu_map(query,region): params=urllib.urlencode({'query':query,'region':region,'output':"xml",'key':"aba6d4d0009d55b95162dc1f107e58a3"}) f=urllib.urlopen("http://api.map.baidu.com/place/search?&%s"% params) return f def readxml(filename): doc=xml.dom.minidom.parse(filename) for node in doc.getElementsByTagName("result"): name=None address=None lat=None lng=None telephone=None NAME=node.getElementsByTagName('name') for node2 in NAME: for node3 in node2.childNodes: if node3.nodeType==Node.TEXT_NODE: name = node3.data ADDRESS=node.getElementsByTagName('address') for node2 in ADDRESS: for node3 in node2.childNodes: if node3.nodeType==Node.TEXT_NODE: address = node3.data TEL=node.getElementsByTagName('telephone') for node2 in TEL: for node3 in node2.childNodes: if node3.nodeType==Node.TEXT_NODE: telephone = node3.data LOC=node.getElementsByTagName('location') for node2 in LOC: for node3 in node.getElementsByTagName('lat'): for node4 in node3.childNodes: if node4.nodeType==Node.TEXT_NODE: lat =node4.data for node3 in node.getElementsByTagName('lng'): for node4 in node3.childNodes: if node4.nodeType==Node.TEXT_NODE: lng =node4.data print "name=%s,address=%s,TEL=%s,location=%s,%s"%(name,address,telephone,lat,lng) if __name__=="__main__": if(len(sys.argv)==3): query=sys.argv[1] region=sys.argv[2] result=baidu_map(query,region) fd=open('result','wb') fd.write(result.read()) fd.close() else: print "参数不对" readxml('result')
返回结果如下:
