本文实例讲述了python解析xml文件操作的实现方法。分享给大家供大家参考。具体方法如下：
xml文件内容如下：
sample xml thing ma xiaoju springs widgets, inc. first i think widgets are greate.you should buy lots of them forom spirngy widgts, inc
python代码：
from xml.dom import minidom, node import re, textwrap class samplescanner: def __init__(self, doc): constructor assert(isinstance(doc, minidom.document)) for child in doc.childnodes: if child.nodetype == node.element_node and \ child.tagname == book: self.handle_book(child) def handle_book(self, node): for child in node.childnodes: if child.nodetype != node.element_node: continue if child.tagname == title: print book titile is:, self.gettext(child.childnodes) if child.tagname == author: self.handle_author(child) if child.tagname == chapter: self.handle_chapter(child) def handle_chapter(self, node): number = node.getattribute(number) print number:, number title_node = node.getelementsbytagname(title) print title:, self.gettext(title_node) for child in node.childnodes: if child.nodetype != node.element_node: continue if child.tagname == para: self.handle_chapter_para(child) def handle_chapter_para(self, node): company = company = self.gettext(node.getelementsbytagname(company)) print chapter:para:company, company def handle_author(self, node): for child in node.childnodes: if child.nodetype != node.element_node: continue if child.tagname == name: self.handle_author_name(child) if child.tagname == affiliation: print affiliation:, self.gettext(child.childnodes) def handle_author_name(self, node): first = last = for child in node.childnodes: if child.nodetype != node.element_node: continue if child.tagname == first: first = self.gettext(child.childnodes) if child.tagname == 'last': last = self.gettext(child.childnodes) print firstname:%s,lastname:%s % (first, last) def gettext(self, nodelist): retlist = [] for node in nodelist: if node.nodetype == node.text_node: retlist.append(node.wholetext) elif node.haschildnodes: retlist.append(self.gettext(node.childnodes)) return re.sub('\s+', , ''.join(retlist)) if __name__==__main__: doc = minidom.parse(simple.xml) sample = samplescanner(doc)
希望本文所述对大家的python程序设计有所帮助。
