The answer is yes, and the String class do it well.

I suggest to learn Java from the official tutorial, the chapter for Strings is here.

For a more powerful method to extract parts of string, the Regular Expressions may be used.
The main class to deal with RE is java.util.regex.Pattern and their official tutorial is here. Another tutorial resource is here.

Save part of a String from a word to a different word
I am trying to learn, through trial and error, how to get values from parameters that are declared in the ParameterBindings section in an XSLTListViewWebPart through SharePoint Designer.

I have noticed that occasionally, when I make a change to the web part that I am guessing is not well formed, I see no change to the SharePoint page when I refresh the browser.

What I am wondering is where could I see the error message associated with my ill-formed XSLT? 

In SharePoint designer I don't see an Errors or Output window that would show the progress as my saved changes to the web part get published to my site.  I also tried looking at my machine's Event Viewer and couldn't find any errors associated with my publishes.  Finally, I looked at the ULS logs while I was publishing and while I was requesting the changed page and I don't see any errors coming through at those times.

What is the best approach to track errors when publishing from SharePoint Designer?
