XLinks are one-to-many links based on the principle that each topic contains one or more keywords. When you create a link, you add keywords belonging to topics to which you would like to link. When a user clicks an XLink, one of the following two things can happen:
If only one topic is associated with the link, the user directly accesses the topic.
If more than one topic is associated with the link, a table or menu-style list of links is displayed. The user can then choose a topic.
XLinks are useful in situations where you need to link to more than one topic from a single link. They can also be used for linking to content stored in a different compiled Help (.HxS) file. To create XLinks with a one-to-one relationship, each topic must contain one keyword that is unique to that topic. This is the keyword that will be used when linking to a single topic stored in an external .HxS file.
The following example shows the markup that can be used in an XLink.
= "data;search" <!-- Required -->
= "0" <!-- Required -->
= "table | menu"
