XSLT transformation with loop in XML node

So my XML follows...

<Classes_Per_Term>  
<Course>ENC1101</Course>
<Ref_Code>111111</Ref_Code>
<Days_of_Week>M</Days_of_Week>
</Classes_Per_Term>
<Classes_Per_Term>  
<Course>ENC1101</Course>
<Ref_Code>111222</Ref_Code>
<Days_of_Week>M W F</Days_of_Week>
</Classes_Per_Term>  

I need output to look like this

ENC1101 111111 M

ENC1101 111222 M

ENC1101 111222 W

ENC1101 111222 F

I am calling the course and Ref with a value-of call and using an insert line call to hop to the next row. I am unsure how to set a loop inside the Days of Week node. There are all sorts of Day combinations - I need a row for each day a specific reference meets.

Any help is appreciated. Thanks!
