我有一些代码。它旨在迭代一个文件夹,找到两个点并删除这两个点之间的所有内容,例如,
<head>
<title>This is bad HTML</title>
</head>
<body>
<h1> Remove me</h1>
<div class="title">
<h1> This is the good data, keep me</h1>
<p> Keep this text </p>
</div>
<div class="footer">
<h1> Remove me, I am pointless</h1>
</div>
</body>
应该去:
<div class="title">
<h1> This is the good data, keep me</h1>
<p> Keep this text </p>
</div>
如果你的两点是:
start=<div class="title">
end=<div class="footer">
奇特之处 - 当我调用Python函数print来实现这一点时,代码完美地运行并且符合预期。
当我保存到文件时,生成的.html仅包含start
和end
元素。我尝试打印出变量的每个值和每个可能的输出。这一切在打印到控制台时都有意义,但在保存到文件时会混乱。
这里发生了什么?
以下是代码:
import os
dir = os.listdir("C:/Users/FOLDER")
files = []
for file in dir:
if file[-5:] == '.html':
files.insert(0, file)
for fileName in files:
file = open("C:/Users/FOLDER/" + fileName)
content = file.read()
file.close()
start = content.find('<div class="title">')
end = content.find('<div class="footer">')
print "Start => " + start.__str__() #This is -1 if nothing found
print "End =>" + end.__str__() #Same
start = start if (start != -1) else 0 #Removing -1 if found
end = end if (end != -1) else len(content) #Same
print "Edited start => " + start.__str__() #Verifying -1 changed
print "Edited end -> " + end.__str__() #Same
print "CONTENTS=========>>>>>>>>>>>>>" + content[start:end-1] #prints perfectly fine
#newContent = content[start:end-1]
file = open("C:/Users/FOLDER/" + fileName[0:-5] + "_mod" + ".html", 'w')
file.write(content[start:end]) #Writes only the start and end nodes to file, example below
file.close()
这将保存到我的html,附加_mod:
<div class="title">
<h1>Title</h1>
</div>
</div>
<div class="footer">
除此之外,尽管在标题和页脚div之间有大量文字 - 尽管它在控制台中正确打印!
我在这里忽略了什么吗?看起来像一个新奇的小虫!
