I have two arrays of text and XML tags and I'm trying to figure out which match up. Many of the tags are nested in other tags and may or may not exist at all in the other array For example 
@array1 = ("Here ","<Tag Id=1>","is","</Tag>"," an ","<Tag Id=2>",
"example that ","<Tag Id=3>","I","</Tag>"," just made","</Tag>")

@array2 = ("<Tag Id=7>","Here is","</Tag>"," an ","<Tag Id=8>",
"example that I just made","</Tag>")

Or shown joined up for easier reading 
Array 1 =  Here <Tag Id=1>is</Tag> an <Tag 2>example that <Tag Id=3>
I</Tag> just made</Tag>

Array 2 = <Tag Id=7>Here is</Tag> an <Tag 2>example that I just 
made</Tag>

As you can see (or perhaps not, my example isn't great) tag2 in @array1 matches tag 8 in @array2 while the other tags simply don't match up. The way that I've been attempting to solve this at the minute is simply by tracking how much of the actual text I've been through and using a heap of if statments to determine what to do. But it is quite long, and very hard to read. I'm thinking there must must be an easier way to do this, perhaps by filtering the array in some manner so that the tags that match can be easily mapped together. Or perhaps there is no easy solution. How would all you clever perl people go about solving a problem like this?
