Question

我想在ObjectUnionOf(和之后的第一个封闭括号之间进行提取：

<http://www.ifomis.org/bfo/1.1/spanScatteredTemporalRegion> <http://www.ifomis.org/bfo/1.1/spanConnectedTemporalRegion>

这

EquivalentClasses(<http://www.ifomis.org/bfo/1.1/spanTemporalRegion> ObjectUnionOf(<http://www.ifomis.org/bfo/1.1/spanScatteredTemporalRegion> <http://www.ifomis.org/bfo/1.1/spanConnectedTemporalRegion>))

我试过了：

content=content[content.find("ObjectUnionOf(")+1:content.find(")")]

但它不起作用

Answer 1

使用正则表达式：

import re
s = "EquivalentClasses(<http://www.ifomis.org/bfo/1.1/spanTemporalRegion> ObjectUnionOf(<http://www.ifomis.org/bfo/1.1/spanScatteredTemporalRegion> <http://www.ifomis.org/bfo/1.1/spanConnectedTemporalRegion>))"
m = re.search("ObjectUnionOf\((?P<links>.*?)\)", s)
if m:
    print( m.group('links') )

<强>输出：

<http://www.ifomis.org/bfo/1.1/spanScatteredTemporalRegion> <http://www.ifomis.org/bfo/1.1/spanConnectedTemporalRegion>

Answer 2

使用re.findall：

import re

txt = '''EquivalentClasses(<http://www.ifomis.org/bfo/1.1/spanTemporalRegion> ObjectUnionOf(<http://www.ifomis.org/bfo/1.1/spanScatteredTemporalRegion> <http://www.ifomis.org/bfo/1.1/spanConnectedTemporalRegion>))'''

print('\n'.join(re.findall(r'ObjectUnionOf\((.*)\)\)', txt)))

# <http://www.ifomis.org/bfo/1.1/spanScatteredTemporalRegion> 
# <http://www.ifomis.org/bfo/1.1/spanConnectedTemporalRegion>
