我有多个XML文件(60多个),需要编辑多个文本节点(我认为这被称为)。我熟悉Java,JavaScript,Python,JQuery,PHP,HTML。
我可以用什么语言来完成?
这是我当前拥有的样本XML文档的内容:
<?xml version="1.0" encoding="utf-8"?><bookstore>
<book category="cooking">
<title lang="en">Chinese</title>
<author>chinese author</author>
<year>2015</year>
<price>fourth</price>
</book>
<book category="cooking">
<title lang="en">All American</title>
<author>American Author</author>
<year>2015</year>
<price>6.00</price>
</book>
</bookstore>
因此,例如,我想一次更改多个元素的作者和年份!
这是我的python代码,它将一次编辑一个节点。我需要一个循环或一些东西来一次编辑更多内容。
from xml.dom.minidom import parse
import os
# create a backup of original file
new_file_name = 'dom.xml'
old_file_name = new_file_name + "~"
os.rename(new_file_name, old_file_name)
# change text value of element
doc = parse(old_file_name)
node = doc.getElementsByTagName('author')
node[0].firstChild.nodeValue = 'new author'
# persist changes to new file
xml_file = open(new_file_name, "w")
doc.writexml(xml_file, encoding="utf-8")
xml_file.close()
任何帮助将不胜感激。新手程序员在这里!
谢谢你!:D
创建函数:
def create_backup(new_file_name):
""" create a backup of original file """
old_file_name = new_file_name + "~"
os.rename(new_file_name, old_file_name)
return old_file_name
def change_author(doc, new_author)
""" change text value of 'author' """
node = doc.getElementsByTagName('author')
node[0].firstChild.nodeValue = new_author
def save_changes(new_file_name, doc):
""" persist changes to new file """
xml_file = open(new_file_name, "w")
doc.writexml(xml_file, encoding="utf-8")
xml_file.close()
现在很容易创建循环:
file_names = ['dom.xml', ...]
for new_file_name in file_names:
old_file_name = create_backup(new_file_name)
doc = parse(old_file_name)
change_author(doc, 'new author')
save_changes(new_file_name, doc)
