xml - 使用 xmllint 返回多个结果

Question

我正在尝试提取包含指定标记的 XML 文件的所有部分。我在网上搜索了一下，发现这个很管用。

xmllint --xpath "/all/string(//title)"

但是它只返回第一个结果，我怎样才能让它找到所有结果呢？谢谢!

我无法让它以您想要的方式仅与 xmllint 一起工作。最接近的是:

 xmllint --xpath "//something/programme/title/text()" test.xml

但这会在一行中为您提供所有输出。

对我来说最好的解决方案是:

xmllint --xpath "//something/programme/title" test.xml | sed 's/<\/title>/\n/g' | sed 's/<title lang="eng">//g'

当然，您可以使用任何其他工具来清理输出。
