Handling Namespaces in XML Tags

See more XML Examples

Demonstrates new features added in Chilkat v9.5.0.77 for helping with namespace prefixed tags. Ruby

require 'chilkat'

# First create some XML using namespace prefixed tags.

# Create this XML. 
# Use this online tool to generate the code from sample XML: 
# Generate Code to Create XML

# <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
#    xmlns:scm="http://www.springcm.com/atlas/webservices/v201308/scm/">
#    <soapenv:Header/>
#    <soapenv:Body>
#       <scm:AccountGetCurrent>
#          <scm:token>123</scm:token>
#       </scm:AccountGetCurrent>
#    </soapenv:Body>
# </soapenv:Envelope>

xml = Chilkat::CkXml.new()
xml.put_Tag("soapenv:Envelope")
xml.AddAttribute("xmlns:soapenv","http://schemas.xmlsoap.org/soap/envelope/")
xml.AddAttribute("xmlns:scm","http://www.springcm.com/atlas/webservices/v201308/scm/")
xml.UpdateChildContent("soapenv:Header","")
xml.UpdateChildContent("soapenv:Body|scm:AccountGetCurrent|scm:token","123")

# Go to the "Body" tag, regardless of namespace prefix.
# xmlBody is a CkXml
xmlBody = xml.FindChild("*:Body")
if (xml.get_LastMethodSuccess() != true)
    print "Body child not found." + "\n";
    exit
end

# Get the full tag w/ namespace prefix:
# Output is "soapenv:Body"
print xmlBody.tag() + "\n";

# Get the namespace prefix:
# Output is "soapenv"
print xmlBody.tagNsPrefix() + "\n";

# Get the unprefixed tag:
# Output is "Body"
print xmlBody.tagUnprefixed() + "\n";

# Check to see if the unprefixed tag equals "Body"
isBodyTag = xmlBody.TagUnpEquals("Body")
print "isBodyTag = " + isBodyTag.to_s() + "\n";

# Check to see if the namespace prefix equals "soapenv";
isSoapenv = xmlBody.TagNsEquals("soapenv")
print "isSoapenv = " + isSoapenv.to_s() + "\n";

# Change just the namespace prefix of the tag
xmlBody.put_TagNsPrefix("se")
# The tag has changed from "soapenv:Body" to "se:Body"
print xmlBody.tag() + "\n";

# Change the unprefixed part of the tag.
xmlBody.put_TagUnprefixed("Bodie")
# The tag has changed from "se:Body" to "se:Bodie"
