[jira] [Commented] (GROOVY-7576) NamespaceBuilder does not add namespace declaration to the generated xml

["Paul King (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-7576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14732335#comment-14732335 ] 

Paul King commented on GROOVY-7576:
-----------------------------------

Looks like a regression in {{MarkupBuilder}} that will need further investigation. It certainly worked in the past, e.g. see GROOVY-3282 but doesn't seem to work now, so I guess we don't have anything quite like that in our test suite.

In the meantime you could use NodeBuilder, e.g.:
{code}
import groovy.xml.XmlUtil
import groovy.xml.NamespaceBuilder

def writer  = new StringWriter()
def builder = NodeBuilder.newInstance()
def xsd     = new NamespaceBuilder(builder).namespace('http://www.w3.org/2001/XMLSchema', 'xs')

def root = xsd.schema() {}
println XmlUtil.serialize(root)
root = xsd.schema("xmlns:xs": 'http://www.w3.org/2001/XMLSchema') {}
println XmlUtil.serialize(root)
{code}

> The code bellow produces the same XSD, both without the xmlns:xs attribute. It was tested in groovy console today:

> {code}
> import groovy.xml.MarkupBuilder
> import groovy.xml.NamespaceBuilder
> def writer  = new StringWriter()
> def builder = new MarkupBuilder(writer)
> def xsd     = new NamespaceBuilder(builder).namespace('http://www.w3.org/2001/XMLSchema', 'xs')
> xsd.schema() {}
> writer.toString()
> xsd.schema("xmlns:xs": 'http://www.w3.org/2001/XMLSchema') {}
> writer.toString()
> {code}
