Question

在两个值之间提取文本的正则表达式是什么？

在：

<office:annotation office:name="__Annotation__45582_97049284">
</office:annotation>
    case 1 there can be an arbitrary text with any symbols
<office:annotation-end office:name="__Annotation__45582_97049284"/>

<office:annotation office:name="__Annotation__19324994_2345354">
</office:annotation>
    case 2there can be an arbitrary text with any symbols
<office:annotation-end office:name="__Annotation__19324994_2345354"/>

出：

list = [
'case 1 there can be an arbitrary text with any symbols',
'case 2 there can be an arbitrary text with any symbols',
]

Answer 1

使用XML解析器更好，如果你想要一个正则表达式解决方案，那么试试下面的，

>>> str = """<office:annotation office:name="__Annotation__45582_97049284">
... </office:annotation>
...     case 1 there can be an arbitrary text with any symbols
... <office:annotation-end office:name="__Annotation__45582_97049284"/>
... 
... <office:annotation office:name="__Annotation__19324994_2345354">
... </office:annotation>
...     case 2there can be an arbitrary text with any symbols
... <office:annotation-end office:name="__Annotation__19324994_2345354"/>"""
>>> m = re.findall(r'<\/office:annotation>\s*(.*)(?=\n<office:annotation-end)', str)
>>> m
['case 1 there can be an arbitrary text with any symbols', 'case 2there can be an arbitrary text with any symbols']

OR

一个更好的正则表达式，

<\/office:annotation>([\w\W\s]*?)(?=\n?<office:annotation-end)

Answer 2

由于这是一个命名空间的XML文档，因此在选择节点时必须处理这些命名空间。有关详细信息，请参阅this answer。

以下是使用lxml和xpath表达式解析它的方法：

<强> data.xml中

<?xml version='1.0' encoding='UTF-8'?>
<document xmlns:office="http://www.example.org/office">

    <office:annotation office:name="__Annotation__45582_97049284">
    </office:annotation>
        case 1 there can be an arbitrary text with any symbols
    <office:annotation-end office:name="__Annotation__45582_97049284"/>

    <office:annotation office:name="__Annotation__19324994_2345354">
    </office:annotation>
        case 2there can be an arbitrary text with any symbols
    <office:annotation-end office:name="__Annotation__19324994_2345354"/>

</document>

<强> parse.py

from lxml import etree

tree = etree.parse('data.xml')
root = tree.getroot()
nsmap = root.nsmap

annotations = root.xpath('//office:annotation', namespaces=nsmap)

comments = []
for annotation in annotations:
    comment = annotation.tail.strip()
    comments.append(comment)

print comments

输出：

['case 1 there can be an arbitrary text with any symbols',
 'case 2there can be an arbitrary text with any symbols']

Answer 3

>>> regex = re.compile(r'</.+>\s*(.+)\s*<.+>')
>>> matched = re.findall(regex, text)
>>> print(matched)
['case 1 there can be an arbitrary text with any symbols', 'case 2there can be an arbitrary text with any symbols']

编辑：我们走了。呸..这些编辑点。
