GPath

GPath is a path expression language we've integrated into Groovy which is similar in aims and scope as XPath is to XML.

import groovy.util.*

def text = """
<languages>
    <language id="1" name="Java">
        <attention>Spring</attention>
        <attention>Hibernate</attention>
        <attention>MyFaces</attention>
        <attention>Groovy</attention>
        <attention>Seam</attention>
        <attention>XFire</attention>
        <attention>Liferay</attention>
    </language>
    <language id="2" name="Python">
        <attention></attention>
    </language>
</languages>
"""

def node = new XmlParser().parseText(text)

def languages = node.children()
for (language in languages) {
    println language['@name']
}

def attentions = node.language.find { it['@id'] == '1' }.attention
for (attention in attentions) {
    println attention.parent()['@name'] + ",  " + attention.text()
}
