Groovy：从文件中读取xml并向其添加节点

我在位置（C:/Users/abc.XML）有一个XML文件abc.XML，我想通过添加一个模块依赖项来更新它

abc.xml

<?xml version="1.0" encoding="UTF-8"?>

<module xmlns="urn:jboss:module:1.3" name="org.picketbox">
    <!-- This module is deprecated and subject to being removed in a subsequent release. -->
    <properties>
      <property name="jboss.api" value="deprecated"/>
    </properties>

    <resources>
        <resource-root path="picketbox-4.9.6.Final.jar"/>
        <resource-root path="picketbox-infinispan-4.9.6.Final.jar"/>
        <resource-root path="picketbox-commons-1.0.0.final.jar"/>
    </resources>

    <dependencies>
        <module name="javax.api"/>
        <module name="javax.persistence.api" optional="true"/>
    </dependencies>
</module>

这不是没有任何错误的工作，相同的代码用于简单xml（没有任何注释，只有一个节点）文件。

试试这个

import groovy.xml.QName
import groovy.xml.XmlUtil

def xml = new File("C:/Users/abc.xml").text
def parser = new XmlParser()
def root = parser.parseText(xml)
def numberOfResults = parser.createNode(root.dependencies[0], new QName("module"), ["name":"javax.xyz"])
println XmlUtil.serialize(root)

您可以参考此处的文档

import groovy.xml.QName
import groovy.xml.XmlUtil

def xml = new File("C:/Users/abc.xml").text
def parser = new XmlParser()
def root = parser.parseText(xml)
def numberOfResults = parser.createNode(root.dependencies[0], new QName("module"), ["name":"javax.xyz"])
println XmlUtil.serialize(root)
