XmlSlurper to parse XML and get value of inside elements using Groovy
Question
I am trying to parse the below XML:
<body>
<section id="5f884f20-6638-461f-a3f5-3d237341c048" outputclass="definition_and_scope">
<title>Definition and Scope</title>
<p>A work that is modified for a purpose, use, or medium other than that for which it was originally intended.</p>
<p>This relationship applies to changes in form or to works completely rewritten in the same form.</p>
</section>
<section id="a7cf019f-dc82-46e2-b5ae-2e947d3c2509" outputclass="popup:ready_reference">
<title>Element Reference</title>
<div id="8472e205-3a32-40e3-a7ea-8bd7dbd43715" outputclass="iri">
<p id="e6ddf17a-6b4b-4de3-886e-a315d88545ea" outputclass="title">

</p>
<p id="c69f6279-27a3-4cd8-84a6-bb2c5a7b0424">

</p>
</div>
<div id="3e979983-cbac-4982-84c7-57ae9756e2bb" outputclass="domain">

</p>
</div>
</section>
</body>
I want to extract the values of all the p tags inside of section & section/div and append that value to a stringbuilder.
Here is my code:
def docText = new StringBuilder();
def bodyObject = doc.topic.body.toXmlString(true) //I have only pasted a part of my XML in this question. My XML starts with a doc/topic/body etc
def parseBodyObject = new XmlSlurper().parse(new InputSource(new StringReader(bodyObject)));
def findAllSection = parseBodyObject.depthFirst().findAll{it.name()=='section'}
findAllSection.each {section->
docText.append(" " +section.p)
docText.append(" " +section.div.p + " ")
}
Output: My docText looks like below:
A work that is modified for a purpose, use, or medium other than that for which it was originally intended.This relationship applies to changes in form or to works completely rewritten in the same form. IRIhttp://rdaregistry.info/Elements/w/P10142DomainWorkRangeWorkAlternate labelsUser tasksRecording methodsDublin Core TermsMARC 21 Bibliographic Recording an unstructured descriptionRecording a structured descriptionRecording an identifierRecording an IRI For the inverse of this element, see Work: adapted as work For broader elements, see Work: based on workFor narrower elements, see
I am stuck at adding a space between text. For eg. When it is going through section/div/p, it is adding all the p together without any spaces as below:
IRIhttp://rdaregistry.info/Elements/w/P10142DomainWorkRangeWorkAlternate
which should output as(expected output):
IRI http://rdaregistry.info/Elements/w/P10142 Domain Work
How should I get these values separated? Any help is appeciated.

I believe that this depthFirst().findAll { it.name() == 'section'} returns an array list which element is a combination of the inner text of p tags.
Let's define your sample XML as xmlDoc . Below is the snippet of code that works as expected:
def parseBodyObject = new XmlSlurper().parseText(xmlDoc)
def findAllPtags = parseBodyObject.children().depthFirst().findAll {
it.name() == 'p'
}
def docText = new StringBuilder()
findAllPtags.each { p ->
docText.append("\n" + p)
}
You can replace \\n by a space.
