Regex 在UNIX中使用SED命令替换整个字符串

regex bash shell unix sed

Regex 在UNIX中使用SED命令替换整个字符串,regex,bash,shell,unix,sed,Regex,Bash,Shell,Unix,Sed,我有下面的XML <?xml version='1.0' encoding='UTF-8'?> <refdataContent xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://www.orbitz.com/refdataContent file:///opt/orbitz/schemas/content/refdataContent/1/0/refdataConte

我有下面的XML

<?xml version='1.0' encoding='UTF-8'?>
<refdataContent xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://www.orbitz.com/refdataContent file:///opt/orbitz/schemas/content/refdataContent/1/0/refdataContent.xsd' xmlns='http://www.orbitz.com/refdataContent'>

  <entry key='com.orbitz.reference.api.hotel.HotelPlacementMetagyType.PREMIUMPLACEMENT'><![CDATA[Premium Placement]]></entry>
  <entry key='com.orbitz.reference.api.hotel.HotelAvailability.AVAILABLE'><![CDATA[Available]]></entry>
</refdataContent>

需要替换XML头吗

<refdataContent xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'xsi:schemaLocation='http://www.orbitz.com/refdataContent file:///opt/orbitz/schemas/content/refdataContent/1/0/refdataContent.xsd'xmlns='http://www.orbitz.com/refdataContent'> </refdataContent>

作为使用SED命令

帮助？

关于sed-i的/refdataContent/properties/g'yourfile.xml呢？

很难准确理解您想要做什么，我将尝试几个选项

鉴于以下情况：

$ cat blah.xml
<?xml version='1.0' encoding='UTF-8'?>
<refdataContent xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://www.orbitz.com/refdataContent file:///opt/orbitz/schemas/content/refdataContent/1/0/refdataContent.xsd' xmlns='http://www.orbitz.com/refdataContent'>

  <entry key='com.orbitz.reference.api.hotel.HotelPlacementMetagyType.PREMIUMPLACEMENT'><![CDATA[Premium Placement]]></entry>
  <entry key='com.orbitz.reference.api.hotel.HotelAvailability.AVAILABLE'><![CDATA[Available]]></entry>
</refdataContent>

将该行替换为：

要将行换行，请执行以下操作：

你是说改变

<refdataContent xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'xsi:schemaLocation='http://www.orbitz.com/refdataContent file:///opt/orbitz/schemas/content/refdataContent/1/0/refdataContent.xsd'xmlns='http://www.orbitz.com/refdataContent'>

为什么要求您使用sed？您应该改用为XML设计的工具。您是说要将refdataContent标记的名称更改为属性吗？如果它能很好地处理整个文本，为什么要使用正则表达式？正则表达式只有在需要某种泛化时才有用，并且只有在某种泛化是可接受的情况下才可能使用。@TomFenech Yes我想使用命令sedI将标记更改为refdatacontent我想用删除整行。有没有办法用正则表达式查找和替换？好吧，我误解了你的问题。然后勾选“华盛顿·盖德斯”的答案。
