loading content from xml file when user is another page

[jquan]

I have created a web page, using HTML. my web page is divided by two section. left side is sidebar link section and another one is content area, where i am displaying the text.when user will click the link. suppose he click the first link, then i am loading the first node content from a xml file. If he click the second then second node. it is working fine in same page. But the problem is : I am having another web page. there also same links are there. So when user is in that page and he click the link from there. So from that page how i will target the second page. for the displaying the content.Thanks,Naresh kumar
