删除与正则表达式工具XML标记 [英] Remove XML tags with Regex tools

问题描述

下面是我的XML文件中的一个片段

Here is a snippet of my XML file

<layoutItems>
            <behavior>Edit</behavior>
            <field>ID</field>
</layoutItems>
<layoutItems>
            <page>lastViewedAccount</page>
            <showLabel>false</showLabel>
            <showScrollbars>false</showScrollbars>
            <width>100%</width>
</layoutItems>
<layoutItems>
            <behavior>Required</behavior>
            <field>Name</field>
</layoutItems>

我要删除的部分，中间即

I want to remove the section in the middle i.e

<layoutItems>
            <page>lastViewedAccount</page>
            <showLabel>false</showLabel>
            <showScrollbars>false</showScrollbars>
            <width>100%</width>
</layoutItems>

这部分可以在任何地方的文件中与其他标记一起出现。

This section can appear anywhere inside the file along with other tags.

什么是使用一些字符串操作工具来删除这个的最佳方式？我一直在试图与的sed ，但没有成功，我的运气。任何帮助将是AP preciated。

What is the best way of using some string manipulation tool to remove this? I have been been trying my luck with sed but no success. Any help would be appreciated.

推荐答案

请注意：你应该提供尽可能多的信息，你可以。说到一般解析 HTML ，的 XML ，的 JSON 等用的正则表达式它的不可以是一个好主意，用一个总的 HTML的解析 - 和的 XML解析 - 工具！以下 SED code可以帮助你的平均时间。所以，还请注意：可能的失败与其他文件和其他结构！ 不要在生产中不能使用！我假设否保修！

Please note: you should provide as much information as you can. Speaking generally parsing of html, xml, json and so on with regex it not a good idea, use always a html-parsing- and xml-parsing -tool! The following sed code may help you in the mean time. And so please also note: it may FAIL with other files and other structures! Do not use in production! I assume NO warranty!

sed -r '/<layoutItems>/{:ka;N;s#(</layoutItems>)#\1#;Tka;s/lastViewedAccount//;T;d}' file

Inputfile中有2 lastViewedAccount 标签：

    <?xml version="1.0" encoding="UTF-8"?>
    <Layout xmlns="http://test.com/2006/04/metadata">
        <emailDefault>false</emailDefault>
        <headers>PersonalTagging</headers>
        <headers>PublicTagging</headers>
        <layoutSections>
            <customLabel>false</customLabel>
            <detailHeading>false</detailHeading>
            <editHeading>true</editHeading>
