Question

我有以下数据：

<http://dbpedia.org/data/Plasmodium_hegneri.xml> <http://code.google.com/p/ldspider/ns#headerInfo> _:header16125770191335188966549 <http://dbpedia.org/data/Plasmodium_hegneri.xml> .
_:header16125770191335188966549 <http://www.w3.org/2006/http#responseCode> "200"^^<http://www.w3.org/2001/XMLSchema#integer> <http://dbpedia.org/data/Plasmodium_hegneri.xml> .

现在我想将这些数据转换为以下形式 - 这样< >中包含的最后一个字符串出现在它添加了＃@的行之前。

#@ <http://dbpedia.org/data/Plasmodium_hegneri.xml>
<http://dbpedia.org/data/Plasmodium_hegneri.xml> <http://code.google.com/p/ldspider/ns#headerInfo> _:header16125770191335188966549 .

我写了下面的python代码，以便做同样的事情：

infile = open('testnq.nq', 'r')
outfile= open('outFile.ttl','w')
while True:
    inFileLine1=infile.readline()
    if not inFileLine1:
        break #EOF
    splitString=inFileLine1.split(' ')
    line1= "#@ " + splitString[len(splitString)-2]
    outfile.write(line1)
    line2=""
    for num in range (0,len(splitString)-2):
        line2= line2 + splitString[num]
    outFile.write(line2)

outFile.close()

但我无法获得所需位置的空间。有人可以建议我如何在python或使用linux命令

中做同样的事情

由于存在使用正则表达式和使事情复杂化的风险，这可能有效：

import re

line = """<http://dbpedia.org/data/Plasmodium_hegneri.xml> <http://code.google.com/p/ldspider/ns#headerInfo> _:header16125770191335188966549 <http://dbpedia.org/data/Plasmodium_hegneri.xml> ."""
print re.sub('^(?P<before>.*)(?P<match>\<[^>]+\>)(?P<after>[^<]*)$', '#@ \g<match>\n\g<before>\g<after>', line)

line = """_:header16125770191335188966549 <http://www.w3.org/2006/http#responseCode> "200"^^<http://www.w3.org/2001/XMLSchema#integer> <http://dbpedia.org/data/Plasmodium_hegneri.xml> ."""
print re.sub('^(?P<before>.*)(?P<match>\<[^>]+\>)(?P<after>[^<]*)$', '#@ \g<match>\n\g<before>\g<after>', line)

输出：

#@ <http://dbpedia.org/data/Plasmodium_hegneri.xml>
<http://dbpedia.org/data/Plasmodium_hegneri.xml> <http://code.google.com/p/ldspider/ns#headerInfo> _:header16125770191335188966549  .
#@ <http://dbpedia.org/data/Plasmodium_hegneri.xml>
