Compile the sample validate validation hook by executing ant (see build.xml) in samples/check_links/. The build creates checklinks.jar. Then test the validation hook by proceeding as follows:
Copy checklinks.incl and checklinks.jar to .XXE_install_directory/addon/config/xhtml/
Include checklinks.incl anywhere in by adding the following XXE_install_directory/addon/config/xhtml/xhtml_strict.xxeinclude element in XMLmind XML Editor - Configuration and Deployment:
<include location="checklinks.incl" />
Delete directory (which is equivalent to clearing the Quick Start cache in XMLmind XML Editor - Online Help).XXE_user_preferences_dir/cache/
Restart XXE.
Open samples/tests/in/sample2.html int XXE and examine all the problems found by the validation hook for this file (click on the tool tab to display the semantic warnings).
