最简单的脚本方法来合并两个文本文件 - Ruby，Python，JavaScript，Java？ [英] Easiest scripting method to merge two text files - Ruby, Python, JavaScript, Java?

问题描述

我有两个文本文件，一个包含HTML，另一个包含URL slugs：

I have two text files, one containing HTML and the other containing URL slugs:

文件1（HTML）：

<li><a href="/article/"><button class="showarticle"/><span class="author">Thomas Friedman</span> - <span class="title">The World Is Flat</span></a></li>
<li><a href="/article/"><button class="showarticle"/><span class="author">Michael Dagleish</span> - <span class="title">Scotland In Wartime</span></a></li>
<li><a href="/article/"><button class="showarticle"/><span class="author">Dr. Raymond Kinsella</span> - <span class="title">Progress In Cancer Treatments</span></a></li>
...

文件2（URL SLUGS）：

thomas-friedman-the-world-is-flat
michael-dagleish-scotland-in-wartime
dr-raymond-kinsella-progress-in-cancer-treatments
...

我需要合并它们，以便将FILE 2中的slu插入到FILE 1中的HTML中，如下所示：

I need to merge them so that the slugs in FILE 2 are inserted into the HTML in FILE 1 like this:

输出：

<li><a href="/article/thomas-friedman-the-world-is-flat"><button class="showarticle"/><span class="author">Thomas Friedman</span> - <span class="title">The World Is Flat</span></a></li>
<li><a href="/article/michael-dagleish-scotland-in-wartime"><button class="showarticle"/><span class="author">Michael Dagleish</span> - <span class="title">Scotland In Wartime</span></a></li>
<li><a href="/article/dr-raymond-kinsella-progress-in-cancer-treatments"><button class="showarticle"/><span class="author">Dr. Raymond Kinsella</span> - <span class="title">Progress In Cancer Treatments</span></a></li>

什么是最好的方法，哪种语言最适合以最小的复杂度完成这项任务？

What's the best approach and which language would be most appropriate to accomplish this task with a minimum of complexity?

推荐答案

您需要zip-​​function，大多数语言都有。它的目的是并行处理两个或多个数组。

在Ruby中它将是这样的：

You need zip-function, which is available in most languages. It's purpose is parallel processing of two or more arrays.
In Ruby it will be something like this:

f1 = File.readlines('file1.txt')
f2 = File.readlines('file2.txt')

File.open('file3.txt','w') do |output_file|

    f1.zip(f2) do |a,b|
        output_file.puts a.sub('/article/','/article/'+b)
    end

end

为了压缩更多，你可以做两个数组 f1.zip（f2，f3，...）do | a， b，c，... |

For zipping more, than two arrays you can do f1.zip(f2,f3,...) do |a,b,c,...|
