  1. POGroovy: copy XML elements from one doc to another
    text
    copied!<p>I am new to Groovy and am stuck with a simple problem. All I wanna do is extract certain elements from one XML file and created a new file with it. Here's an example XML, let's use a Maven pom file:</p> <pre><code>&lt;project&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;groupId&gt;com.group&lt;/groupId&gt; &lt;artifactId&gt;artifact&lt;/artifactId&gt; &lt;version&gt;1.4&lt;/version&gt; &lt;dependencyManagement&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;junit&lt;/groupId&gt; &lt;artifactId&gt;junit&lt;/artifactId&gt; &lt;version&gt;4.8.2&lt;/version&gt; &lt;scope&gt;test&lt;/scope&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;/dependencyManagement&gt; </code></pre> <p></p> <p>I know how to parse XML in Groovy:</p> <pre><code>def project = new XmlParser().parse("pom.xml") project.groupId.each{ println it.text() } </code></pre> <p>I also know how to create XML in Groovy:</p> <pre><code>def xml = new groovy.xml.MarkupBuilder() xml.project (){ modelVersion("artifactId") groupId("com.group") artifactId("artifact") } </code></pre> <p>However, I seem to have a problem combining the two. I want, for example, take <em>groupId</em>, <em>artifactId</em> and the whole <em>dependencies</em> tree and create a new XML from it. It can't be that hard and I wanna make use of the Groovy simplicity.</p> <p>Something along those lines (of course this does not work):</p> <pre><code>def newXml= new groovy.xml.MarkupBuilder() newXml.groupId= project.groupId newXml.dependencies = project.dependencyManagement.dependencies </code></pre> <hr> <p>Thanks. That code helped a lot but how can I handle the namespace, i.e. if the project tag in the input looks like that:</p> <pre><code>&lt;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"&gt; </code></pre> <p>It is then adding some weird annotations to the output. All I want is that the project tag in the output looks like that as well.</p>
