我只是刚开始使用Python进行网络抓取,目前我正在使用BeautifulSoup进行数据提取。我有这个.aiml文件(xml),其中我想从 topic 标签内 NOLULUDED 的标签 pattern 中提取所有数据
我已经获得了所有模式值,但是这里的挑战在于,那些具有 topic 父标记的模式不应该包含在结果集中。
这是aiml文件:
<?xml version = "1.0" encoding = "UTF-8"?>
<aiml version="1.0.1" encoding="UTF-8">
<topic name="botdog">
<category>
<pattern>MY DOG'S NAME IS *</pattern>
<template>
That is interesting that you have a dog named <set name="dog"><star/></set>
</template>
</category>
<category>
<pattern>WHAT IS MY DOG'S NAME</pattern>
<template>
Your dog's name is <get name="dog"/>.
</template>
</category>
</topic>
<topic name="botcat">
<category>
<pattern>MY CAT'S NAME IS *</pattern>
<template>
That is interesting that you have a cat named <set name="cat"><star/></set>
</template>
</category>
<category>
<pattern>WHAT IS MY CAT'S NAME</pattern>
<template>
Your cat's name is <get name="cat"/>.
</template>
</category>
</topic>
<category>
<pattern>HELLO ALICE</pattern>
<template>
Hello User
</template>
</category>
<category>
<pattern>HOW ARE YOU</pattern>
<template>
I'm fine
</template>
</category>
</aiml>
Python代码(烧瓶):
@extract.route('/')
def index_page():
folder = 'templates/topic.aiml'
with open(folder, 'r') as myfile:
soup = BeautifulSoup(myfile.read(), 'html.parser')
data_topic = [match.pattern.text for match in soup.find_all('category')]
print(data_topic)
# data = " ".join(data_set)
return jsonify({'data_set': data_topic})
print()返回的值为:
[“我的狗的名字*”,“我的狗的名字是什么”,“我的猫的名字是*”,“我的猫的名字是什么”,“ HELLO ALICE”,“你怎么了”]
仅应这样,因为它没有父标签 topic : ['HELLO ALICE','你好吗']
答案 0 :(得分:0)
尝试一下:
@extract.route('/')
def index_page():
folder = 'templates/topic.aiml'
with open(folder, 'r') as myfile:
soup = BeautifulSoup(myfile.read(), 'html.parser')
data = []
for cat in soup.find_all('category'):
if cat.parent.name == "topic": continue
data += [cat.find("pattern").text]
print(data)
return jsonify({'data_set': data})
