I need help on this.

In my java code, I have a variable which is an ArrayList and the
elements inside are strings.

For example, aList has a type of ArrayList and it has elements "a",
"b","c", "d" ..... (the length of the aList is variable). In my xslt I
have the following code:

<xsl:for-each select="a:aList "><xsl:value-of select="."/>;</xsl:for-each>

the output is
a;
b;
c;
d;
....
But my expected output should be like
a;b;c;d;...;
all the elements need to be on the same line.

Does anybody have any idea how to do it? Thank you very much!
