I know C# but have not worked with anything XML before. I need to delete some nodes from a XML file. Below, the content of the file is shown partially.

I need to find and then delete the oxml:certificado node, located inside the oxml:firmaElectronica node which is the last node shown on my sample XML code.



I am trying to find the oxml:certificado node with this C# code:



XmlNode certificado = doc.SelectSingleNode("/soapenv:Envelope/soapenv:Body/oxml:solicitarRecibirCoveServicio/oxml:comprobantes/oxml:firmaElectronica/oxml:certificado");


But I get the following error:




An unhandled exception of type 'System.Xml.XPath.XPathException'
occurred in System.Xml.dll Namespace Manager or XsltContext needed.
This query has a prefix, variable, or user-defined function.




Any help on finding and deleting this node would be great. Thanks.
