Nokogiri: CSS syntax for XML namespaces

Copy
<soapenv:Envelope> <soapenv:Body> <elem> <nest>...</nest> </elem> </soapenv:Body> </soapenv:Envelope>

CSS selectors are a very simple tool to select elements from a Nokogiri document. However, the colon in the XML namespace syntax does not work with CSS. When selecting namespaced elements, you need to replace their colon (soapenv:Envelope) with a pipe (soapenv|Envelope):

Copy
document = Nokogiri::XML(xml) nest = document.at_css 'soapenv|Envelope soapenv|Body elem nest'
