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. B4X

'  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>

Dim xml As ChilkatXml
xml.Initialize
xml.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.
Dim xmlBody As ChilkatXml = xml.FindChild("*:Body")
If xml.LastMethodSuccess <> True Then
    Log("Body child not found.")
    Return
End If


'  Get the full tag w/ namespace prefix:
'  Output is "soapenv:Body"
Log(xmlBody.Tag)

'  Get the namespace prefix:
'  Output is "soapenv"
Log(xmlBody.TagNsPrefix)

'  Get the unprefixed tag:
'  Output is "Body"
Log(xmlBody.TagUnprefixed)

'  Check to see if the unprefixed tag equals "Body"
Dim isBodyTag As Boolean = xmlBody.TagUnpEquals("Body")
Log("isBodyTag = " & isBodyTag)

'  Check to see if the namespace prefix equals "soapenv";
Dim isSoapenv As Boolean = xmlBody.TagNsEquals("soapenv")
Log("isSoapenv = " & isSoapenv)

'  Change just the namespace prefix of the tag
xmlBody.TagNsPrefix = "se"
'  The tag has changed from "soapenv:Body" to "se:Body"
Log(xmlBody.Tag)

'  Change the unprefixed part of the tag.
