The above example (assuming the > is added to the </foreach) should return the single value "a||B". Please correct the example so the problem is reproducable

<foreach name=p list="a||B" delim="|">
1
</foreach

produces 11 as output

Work around:

Use: <foreach name=i list="A||B" delim="[|]"> ...

Using a single character delimeter uses StringTokenizer(), which collapsed multiple delimiters.
Multiple character delimiters are always interpreted as regular expressions, and empty
values are returned properly

A work around was proposed
