2个变量列表之间的差异TIBCO BW

Question

I have 2 variables. I need to get the difference between them. $var (a,b,c,d) and $var2 (a,b,c,d,e,f,g). How can i do this using xpath funtions? Any help is appreciated.

Thanks in Advance

Answer 1

如果tibco支持XPath 2.0，则可以尝试使用except和union（ | ），如下所示：

$var except $var2 | $var2 except $var

Answer 2

With XPATH 1.0 you can also use the union off diffs of nodesets ( O'Reilly's XSLT Cookbook )

Elements from var not in var1: $var[count(. | $var1) != count($var1)]
Elements from var1 not in var: $var1[count(. | $var) != count($var)]

Therefor try:

$var[count(. | $var1) != count($var1)] | $var1[count(. | $var) != count($var)]
