Description

I am trying to use XmlSlurper to process and xml with nested elements with text in them. I need to get the text from just one level at a time but the text() method returns all text for all childrend and I can't see anything that would bring back just the local.

Here is a sample from the console:

groovy> def model = new XmlSlurper().parseText('<aModel><aParent name="bubba">text<aChild>child text</aChild></aParent></aModel>')

groovy> model.aParent[0].text()

groovy>

groovy>

Result: "textchild text"

John, assigning to you if for nothing else for comment. Given your proposed new method(s) to XmlSlurper it kind of makes sense to try to tackle this at the same time I think. Just assign back (or leave unassigned) if you have no time (though any suggestions would be welcome) or provide a comment if you think the feature request is not warranted and can be done by other means.

This is not a bug - text() does what it is designed to do which is to give you all the text in the element

However there is a need for an additional mechanism to let you handle mixed content as in the example provided.

I'm working on this

I went to write a parser today and was amazed to find I couldn't do this. Has there been any more thought or progress on this? I would also really like some way to get the actual contents of a NodeChild, something like

def model = new XmlSlurper().parseText('<aModel><aParent name="bubba">text<aChild>child text</aChild></aParent></aModel>')

assertEquals "text<aChild>child text</aChild>", model.aParent[0].contents()

I too did not expect this behavior. This is my work around.

public static String groovyTwentyOneFifteen(def parent) {
    String all = parent.text()
    StringBuilder subtract = new StringBuilder()
    parent.children().each {
        subtract.append(it.text())
    }
    return all.substring(0, all.size() - subtract.toString().size())
}

Here is my work around as a closure (based on the XPath text() function) :

def localText = { parent ->
    def children = parent.getAt(0).children
    def result = [] as List
    for (child in children) {
        if (!(child instanceof groovy.util.slurpersupport.Node)) {
            result.add(child)
        }
    }
    return result
}

Applied on the following XML :

<root>aaa<sub-level>bbbb</sub-level>ccc</root>

It gives the following String list :

[aaa, ccc]
