I am still new to groovy. I need to create a flat json file from a nested xml file. I am having a hard time accessing the header fields when I try to create the JSON.
this is the input:
<?xml version="1.0"?>
<Data>
<Record>
<Header>Header01</Header>
<Item>
<TEST>E1</TEST>
<TEST2>Free text</TEST2>
</Item>
</Record>
<Record>
<Header>Header02</Header>
<Item>
<TEST>E2</TEST>
<TEST2>Free text</TEST2>
</Item>
<Item>
<TEST>E3</TEST>
<TEST2>Free text</TEST2>
</Item>
</Record>
Here is my code:
def xml = new XmlSlurper().parse(reader)
def RecordList = xml.'*'.findAll { it->it.name() == 'Record' }
def itemlist = RecordList.'*'.findAll{node ->node.name()== 'Item'}.collect{
row -> row.collectEntries{[TEST: row.TEST.text(), TEST2:row.TEST2.text()]}
}
StringWriter writer = new StringWriter()
StreamingJsonBuilder builder = new StreamingJsonBuilder(writer)
builder {
"Records" itemlist
}
println JsonOutput.prettyPrint(writer.toString())
Output:
{"Records":[{"TEST":"E1","TEST2":"Free text"},{"TEST":"E2","TEST2":"Free text"},
{"TEST":"E3","TEST2":"Free text"}]}
how do I populate the header fields using this method? by the time I create the list of items, I no longer have access to the header fields in the xml.
Not 100% what you mean...
Do you mean this:
def result = new XmlParser().parse(reader)
.Record
.collectMany { record ->
record.Item.collect {
[ Header: record.Header.text(), Test: it.TEST.text(), Test2: it.TEST2.text() ]
}
}
println new JsonBuilder(result).toPrettyString()
Which prints:
[
{
"Header": "Header01",
"Test": "E1",
"Test2": "Free text"
},
{
"Header": "Header02",
"Test": "E2",
"Test2": "Free text"
},
{
"Header": "Header02",
"Test": "E3",
"Test2": "Free text"
}
]
