xmllint未知选项'--xpath' [英] xmllint unknown option '--xpath'

问题描述

我已经在多个地方看到了这种语法(例如，此处 ):

I've seen this syntax several places (eg, here):

xmllint --xpath '/plist/array/string/text()' tmp.xml，用于使用xpath选择器查询特定的XML节点.但是，当我尝试在我的计算机(mac os x snow leopard)上执行此错误时，出现错误Unknown option --xpath.

xmllint --xpath '/plist/array/string/text()' tmp.xml, used to query a particular XML node using an xpath selector. However, I'm getting the error Unknown option --xpath when I try to execute this on my machine (mac os x snow leopard).

更仔细地查看xmllint的手册页，我没有看到--xpath选项的文档...

Looking more closely at the man page for xmllint, I don't see the --xpath option documented...

我在这里完全错过了什么吗?

Am I just totally missing something here?

推荐答案

xmllint --shell tmp.xml <<<'xpath /plist/array/string/text()'

如果您需要使xmllint读取stdin:

If you need to make xmllint to read stdin:

cat /tmp/tmp.xml | xmllint --shell <(cat) <<<'xpath /plist/array/string/text()'
