I was trying with this sed sentence. "sed -n '/<.[Cc]onnector./>/p'" but not look, I'm only able to get the ajp connector.
some ideas?

Answer 1

The following (GNU) sed might work :
sed -n '/<Connector /,/\/>/p'
It prints from the line containing <Connector  up to the line containing the next /> (which can be the same line).
It works with your sample data but could fail under many conditions, such as the tag having children and being closed by a </Connector> rather than self-closing. If your data has enough variation you'll probably want to use an XML selection language such as XPath, in which //Connector would be enough to get you all the Connector nodes whatever their format is.
