xmlstarlet 在模式后替换值 [英] xmlstarlet replace value after pattern

问题描述

我有一个 pom.xml，我想更改以特定模式开始的标签的属性值.

I have a pom.xml, that I want to change the properties values for tags that starting in a certain pattern.

我通常使用 xmlstarlet 来操作 XML，但我从来没有用regex"做过，这可能吗?

I usually use xmlstarlet to manipulate XML but I never did it with "regex", Is that possible?

我的pom.xml是这样的:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <plugins>
                <plugin>

                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.5.1</version>
                </plugin>
        </pluginManagement>
    </build>
    <properties>
        <repository.snapshots.uri>repository/maven-snapshots</repository.snapshots.uri>
        <company.mgrid.common.version>0.8-SNAPSHOT</company.mgrid.common.version>
        <company.mgrid.infra.version>0.8-SNAPSHOT</company.mgrid.infra.version>
        <company.mgrid.globals.version>0.8-SNAPSHOT</company.mgrid.globals.version>
        <java.jdk.version>1.8</java.jdk.version>
    </properties>
</project>

并且我需要将 节点下以 company.mgrid* 开头的所有标签中的值从 0.8-SNAPSHOT 替换为 0.9-SNAPSHOT，

And I need to replace values in all tags under node that starts with company.mgrid* from 0.8-SNAPSHOT to 0.9-SNAPSHOT,

所以输出将是:

<properties>
    <repository.snapshots.uri>repository/maven-snapshots</repository.snapshots.uri>
    <company.mgrid.common.version>0.9-SNAPSHOT</company.mgrid.common.version>
    <company.mgrid.infra.version>0.9-SNAPSHOT</company.mgrid.infra.version>
    <company.mgrid.globals.version>0.9-SNAPSHOT</company.mgrid.globals.version>
    <java.jdk.version>1.8</java.jdk.version>
</properties>

如前所述，我更喜欢用 xmlstarlet 来做这件事，但如果你有一个使用 sed 或任何其他 bash 工具的解决方案，我们将不胜感激.帮助任何人?

As mentioned I prefer to do it with xmlstarlet but if you have a solution with sed or any other bash tool it will be appreciated. Help anyone?

推荐答案

您感兴趣的是 Xpath 函数 starts-with 开始.它是自 Xpath 1.0 以来的标准功能.这允许您执行以下操作:

What you are interested in is the Xpath function starts-with. It is a standard function since Xpath 1.0. This allows you to do :

$ xmlstarlet ed -N N="http://maven.apache.org/POM/4.0.0"        \
                -u "//N:*[starts-with(name(),'company.mgrid')]" \
                -v "0.9-SNAPSHOT" pom.xml
