仅在XML标签更换;从参考进行出口.reflib到BibTeX格式的文件名和完整URL编码中取出，用bash命令

Question

我在参考进行许多参考文献。我试图从参考进行输出时，提供包括中文提供我的文件的文件名。由于软件没有做这在默认情况下，我试图用一个sed命令，包括文件名作为前我出口XML文件中的一个中文提供信息，因此包括文件名。

我可以使用下面的sed命令来部分地做我想做的，但编码“％20”遗骸的URL。我该如何摆脱，在只有中文提供标签？

sed -e 's/\(\ \ \ \ <filename>file:\/\/\/home\/dwickrama\/Desktop\/stevenJonesLab\/papers\)\([^.]*\)\(\.\?\)\(.*\)\(<\/filename>\)/\1\2\3\4\5\n\ \ \ \ <bib_extra\ key=\"File\">article:\.\.\2\3\4:\4<\/bib_extra>/g' NewPapers.reflib > NewPapers.new.reflib

Answer 1

正则表达式和sed不用于处理XML非常好的工具或URL进行解码。

在更完整的脚本语言快速脚本就能够做到这一点更清晰，可靠。例如在Python：

import urllib, urlparse
from xml.dom import minidom

doc= minidom.parse('NewPapers.reflib')
el= doc.getElementsByTagName('filename')[0]
path= urlparse.urlparse(el.firstChild.data)[2]
foldername, filename= map(urllib.unquote, path.split('/')[-2:])

extra= doc.createElement('bib_extra')
extra.setAttribute('key', 'File')
extra.appendChild(document.createTextNode('article:../%s/%s:pdf' % (foldername, filename)))
el.parentNode.insertBefore(extra, el.nextSibling)
doc.writexml(open('NewPapers.new.reflib'))

（我没有包括的功能重现反斜杠逃逸在给定的例子输出，因为它是没有明确究竟是什么格式，最简单的办法是filename= filename.replace(' ', '\\ ')，但我不知道这将是正确的。 ）

Answer 2

所有你需要的是之后添加一行？所以刚打印出来的搜索完毕之后。

#!/bin/bash

s='<bib_extra key="File">article:../Transcription\\ Factor\\ Binding/A\\ Common\\ Nuclear\\ Signal\\ Transduction\\ Pathway\\ Activated\\ by\\ Growth\\ Factor\\ and\\ Cytokine.pdf:pdf</bib_extra>'

awk -vstr="$s" '
/<filename>/{
    print
    print str;next
}
{print}' file
