仅在 XML 标记内替换；使用 bash 命令从 Referencer .reflib 导出为 bibtex 格式，文件名完整并删除 URL 编码

Question

我在Referencer 中有很多参考文献。从 Referencer 导出时，我尝试在 bibtex 文件中包含文件名。由于该软件默认情况下不会执行此操作，因此我尝试在导出之前使用 sed 命令将文件名作为 bibtex 信息包含在 XML 文件中，从而包含文件名。

输入

  <doc>
<filename>file:///home/dwickrama/Desktop/stevenJonesLab/papers/Transcription%20Factor%20Binding/A%20Common%20Nuclear%20Signal%20Transduction%20Pathway%20Activated%20by%20Growth%20Factor%20and%20Cytokine.pdf</filename>

输出

我可以使用以下 sed 命令部分执行我想要的操作，但 URL 编码“%20”仍然保留。我如何仅在 bibtex 标签中摆脱它？

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

Regex 和 sed 并不是处理 XML 或 URL 解码的好工具。

使用更完整的脚本语言的快速脚本将能够更清晰、更可靠地完成它。例如在Python中：（

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'))

我没有在给定的示例输出中包含一个函数来重现反斜杠转义，因为它不清楚到底是什么格式。最简单的方法是 filename= filename.replace(' ' , '\\ ')，但我不确定这是否正确。）

Answer 2

您所需要的只是在 right 之后添加一行？所以搜索完后打印出来就可以了。

#!/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
