示例plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>file:http://ab.cd.com/path/path/:stable</key>
    <dict>

        <string>stable</string>
        <key>Sections</key>
        <array>
            <string>main</string>
        </array>
        <key>Type</key>
        <string>deb</string>
        <key>URI</key>
        <string>http://ab.cd.com/path/path/</string>
    </dict>
    <key>file:http://xyx.domain.com/:./</key>
    <dict>

        </array>
        <key>Type</key>
        <string>deb</string>
        <key>URI</key>
        <string>http://ab.domainCC.com/path/path/</string>

    <key>Values</key>
<dict/>
<key>Version</key>
<integer>1</integer>
</dict>
</plist>

项目的要求仅为“sed”。这些是plist文件中的属性。我如何使用sed以

开头查找键值

file:http://xyx.domain.com

并将其从那里删除

</dict>

最终结果将是：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

尝试这种方式：

$ sed -e '/file:http:\/\/xyx.domain.com/,/<\/dict>/d' filename
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>file:http://ab.cd.com/path/path/:stable</key>
    <dict>
        <key>Distribution</key>
        <string>stable</string>
        <key>Sections</key>
        <array>
            <string>main</string>
        </array>
        <key>Type</key>
        <string>deb</string>
        <key>URI</key>
        <string>http://ab.cd.com/path/path/</string>
    </dict>
