在Bash脚本中转义单引号xmllint xpath查询

我试图在bash脚本中使用xmllint从xmltv文档中查询信息，但在标题中使用单引号的节目标题时遇到了问题。例如：

XML示例：

<programme start="20150106090000 -0500" stop="20150106093000 -0500" channel="I53.28457646.microsoft.com">
        <title lang="en">Daniel Tiger's Neighborhood</title>
        <sub-title lang="en">Safety Patrol; Safety at the Beach</sub-title>
        <desc lang="en">Prince Tuesday visits the school in his crossing guard uniform and helps the children practice safety rules; Daniel and Katerina drift too far from Mom while playing at the beach.</desc>

我试过几种方法来逃避它，包括用双引号括起来，写Tiger's和Tiger

&aposs，我尝试的似乎都没有帮助

感谢您的帮助。谢谢
 在尝试了一点之后，我找到了两种方法。解决方案是在xpath
XPATHPRE“XPATHPOST
之外通过
\'
转义单引号，并将其连接起来，同时将属性/文本保持在
“
的周围

多亏了@EtanReisner，这一切都成功了！：

xmllint --xpath "/tv/programme[title=\"Daniel Tiger's Neighborhood\"]" xmltv.xml

您需要从名为“Daniel Tiger's Neighborary”的标记程序中获取哪些信息？使用
“/tv/program[title='Daniel Tiger's Neighborary']”“
从shell的角度来看应该是可行的，但这无助于解决内部问题。
“/tv/program[title='Daniel Tiger's Neighborary\]”“]“
可能也可行/电视/节目[title='Daniel Tiger's Neighbour']“

但这取决于xmllint和xml引用。@Cyrus游戏的最终目的是获取开始的内容=”属性，以使用“显示标题”、“说明”和“开始时间”作为匹配条件来获取原始的播放日期。这样，我就可以用Plex Media Server接收和查询TheTVDB.com信息的原始播放日期来命名录制内容。@EtanReisner这很有效！：xmllint--xpath“/tv/program[title=\“Daniel Tiger's Neighborary\”]”xmltv.xmlI刚刚尝试了这些行，结果如下：andrew@andyrblank：$xmllint--xpath'/programme/title[text（）=“Daniel Tiger'\''s Neighbour”]'xmltv.xml xpath集为空andrew@andyrblank：$xmllint--xpath'/program/title[text（）=“'Daniel Tiger's Neighbour'”'xmltv.xml警告：未能加载外部实体“Tiger's”警告：未能加载外部实体“Neighborhood”]“XPath错误：未完成的文字xmlXPathEval:求值失败XPath求值失败第二个建议的命令不正确。它需要是

…”“'Daniel Tiger's Neighborhood'”“…

我相信。举个简单的例子，两种解决方案都很有效。下面是我得到的：最小XML

pu'ps

和最小脚本

#/bin/bash xmllint--xpath'/foo/bar[text（）=“pu'\'ps”和@title=“ke'\'ks”]'foo.xml xmllint--xpath'/foo/bar[text（）=“pu''ps'”和@title=“'ke''ks'””foo.xml

。这两个命令最后都显示

pu'ps

@Etan Reisner您的解决方案也适用于我：）示例中缺少空格会导致出现问题。在你的案例中，你不需要引用这个词，但在@AndyRBlank的案例中，你需要引用。

xmllint --xpath '/programme/title[text()="Daniel Tiger'\''s Neighborhood"]' xmltv.xml
xmllint --xpath '/programme/title[text()="'Daniel Tiger\'s Neighborhood'"]' xmltv.xml

xmllint --xpath "/tv/programme[title=\"Daniel Tiger's Neighborhood\"]" xmltv.xml
