Shell – Insert new line after all occurrences of a pattern

sedshell-scriptxml

I have a pmml file containing one line:

<DataField dataType="string" name="class" optype="categorical"><Value value="y0" /><Value value="y1" /><Value value="y2" /><Value value="y3" /><Value value= "y4" /></DataField><DataField dataType="double" name="x0" optype="continuous" /><DataField dataType="double" name="x1" optype= "continuous" /><DataField dataType="double" name="x2" optype="continuo    us" /><DataField dataType="double" name="x3" optype="continuous" /><DataField dataType="double" name="x4" optype="continuous" /><DataField dataType="double" name="x5" optype="continuous" /><DataField dataType="double" name="x6" optype="continuous" /><DataField dataType="double" name="x7" optype="continuous" /><DataField dataType="double" name="x8" optype="continuous" /><DataField dataType="double" name="x9" optype="continuous" /><DataField dataType="double" name="x10" optype="continuous" /><DataField dataType="double" name="x11" optype="continuous" /><DataField dataType="double" name="x12" optype="continuous" /><DataField dataType="double" name="x13" optype="continuous" /><DataField dataType="double" name="x14" optype="continuous" /><DataField dataType="double" name="x15" optype="continuous" /><DataField dataType="double" name="x16" optype="continuous" /><DataField dataType="double" name="x17" optype="continuous" /><DataField dataType="double" name="x18"     optype="continuous" /><DataField dataType="double" name="x19" optype="continuous" /><DataField dataType="double" name="x20" optype="continuous" /><DataField dataType="double" name="x21" optype="continuous" /><DataField dataType="double" name="x22" optype="continuous" /><DataField dataType="double" name="x23" optype="continuous" /></DerivedField></NeuralOutput></NeuralOutputs></NeuralNetwork></PMML>

I want to insert a new line after all of the optype= "continuous" /> occurrences.

I was able to inset the new line between the first optype and the last /> using sed 's:optype.*/>:a&\n:g' test.pmml > new.pmml.

How can I do this for all occurrences of the pattern? (I prefer sed but solutions using other tools are fine as well.)

You can try this with GNU sed or other sed implementations that now also treat \n as newline in the replacement:

sed 's|optype[^>]*/>|&\n|g' test.pmml

POSIXly:

sed 's|optype[^>]*/>|&\
|g' test.pmml
