Character replacement issue...

Hey everyone,

So I'm working on a "Related Articles" option to based off of keywords. I've been able to make it work using objects in a data definition, but I would prefer to use the metadata keywords.

In doing this, I've been unable to separate the different keywords that are added to the metadata. I was going to use the replaceAll option to remove the commas and insert different code to make this happen.

Here's what I'm looking at right now:

In the XML:

<keywords>Alpha, Bravo, Charlie, Delta</keywords>

I've assigned them to the variable " $meta_keywords " and when I use $meta_keywords.value the keywords show up just fine. I've tried the following replaceAll code with no luck:

#set ( $meta_keywords_rev = $meta_keywords.replaceAll("Delta", "Echo") )

All that shows up is "$meta_keywords_rev.value"

Have I missed something? Also, this is my first post. If I need to change something please let me know. :)

   Hi John,

   $meta_keywords_rev is a String object, not an org.jdom.Element object, and the String class does not have a getValue() method. Use the variable $meta_keywords_rev directly as a string.

   Thanks, that helped. Here's another one for the same purpose...

   Is it possible to break up the keywords to use them separately?

   I'm trying to return any articles that contain any of the original page's keywords.

   It all depends on exactly what you want to do. You can use, for example, String.contains(CharSequence s) or String.split(String regex). Check out the Java 8 API.
