我有两个文本文件,一个包含HTML,另一个包含URL链接:
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链接):
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中的段插入到FILE 1中的HTML中,如下所示:
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此任务?
您需要zip功能,该功能在大多数语言中都可用。目的是并行处理两个或多个数组。 在Ruby中将是这样的:
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
要压缩更多,可以执行两个以上的数组 f1.zip(f2,f3,...) do |a,b,c,...|
f1.zip(f2,f3,...) do |a,b,c,...|
