我遇到了以下问题。比方说,我在字典的两个列表中有一些字符串:
left right
british 7
cuneate nucleus Medulla oblongata
Motoneurons anterior
我在文件中有一些测试行,如下所示:
<s id="69-7">British Meanwhile is the studio 7 album by british pop band 10cc 7.</s>
<s id="5239778-2">Medulla oblongata,the name refers collectively to the cuneate nucleus and gracile nucleus, which are present at the junction between the spinal cord and the medulla oblongata.</s>
<s id="21120-99">Terior horn cells, motoneurons located in the spinal.</s>
我想通过以下方式获得输出:
<s id="69-7"><w2>British</w2> Meanwhile is the studio <w2>7</w2> album by <w1>british</w1> pop band 10cc <w2>7</w2>.</s>
<s id="5239778-2"><w2>Medulla oblongata</w2>,the name refers collectively to the <w1>cuneate nucleus</w1> and gracile nucleus, which are present at the junction between the spinal cord and the <w2>medulla oblongata</w2>.</s>
我尝试了以下代码:
import re
def textReturn(left, right):
text = ""
filetext = open(text.xml, "r").read()
linelist = re.split(u'[\n|\r\n]+',filetext)
for i in linelist:
left = left.strip()
right = right.strip()
if left in i and right in i:
i1 = re.sub('(?i)(\s+)(%s)(\s+)'%left, '\\1<w1>\\2</w1>\\3', i)
i2 = re.sub('(?i)(\s+)(%s)(\s+)'%right, '\\1<w2>\\2</w2>\\3', i1)
text = text + i2 + "\n"
return text
但它给了我:
'<s id="69-7">British meanwhile is the studio <w2>7</w2> album by <w1>British</w1> pop band 10cc 7.</s>'.
<s id="5239778-2">Medulla oblongata,the name refers collectively to the <w1>cuneate nucleus</w1> and gracile nucleus, which are present at the junction between the spinal cord and the medulla oblongata.</s>
<s id="21120-99">Terior horn cells, <w1>motoneurons</w2> located in the spinal.</s>
即如果开头和结尾有字符串,则不能标记。
此外,我只想返回那些匹配左右字符串的行,而不是其他行。
请提供任何解决方案!非常感谢!!!
最佳答案
它不会在开头和结尾标记,因为您希望关键字前后有一个或多个空格。
使用 \b
(分词符)代替 \s+
。

实际代码:
import re
dict = [('british','7'),('cuneate nucleus','Medulla oblongata'),('Motoneurons','anterior')]
filetext = """<s id="69-7">British Meanwhile is the studio 7 album by british pop band 10cc 7.</s>
<s id="5239778-2">Medulla oblongata,the name refers collectively to the cuneate nucleus and gracile nucleus, which are present at the junction between the spinal cord and the medulla oblongata.</s>
<s id="21120-99">Terior horn cells, motoneurons located in the spinal.</s>
"""
linelist = re.split(u'[\n|\r\n]+', filetext)
s_tag = re.compile(r"(<s[^>]+>)(.*?)(</s>)")
for i in range(3):
left, right = dict[i]
line_parts = re.search(s_tag, linelist[i])
start = line_parts.group(1)
content = line_parts.group(2)
end = line_parts.group(3)
left_match = "(?i)\\b(%s)\\b" % left
right_match = "(?i)\\b(%s)\\b" % right
if re.search(left_match, content) and re.search(right_match, content):
line1 = re.sub(left_match, '<w1>\\1</w1>', content)
line2 = re.sub(right_match, '<w2>\\1</w2>', line1)
print(line_parts.group(1) + line2 + line_parts.group(3))
这是短期解决方案的基础,但从长远来看,您应该尝试 XML 解析器方法。
