>Description</H2
><P
>It has become common practice to give PIs structured values. The
result is a PI that looks a lot like a start tag with attributes:</P
><P
><?pitarget name1="value1" name2=<TT
CLASS="LITERAL"
>value2</TT
> name3="value <TT
CLASS="LITERAL"
>3</TT
>"></P
><P
>This function parses a PI with this form and returns a list. The
list contains the pitarget and each of the name/value pairs:</P
><P
>("pitarget" "name1" "value1" "name2" "value2" "name3" "value <TT
CLASS="LITERAL"
>3</TT
>")</P
