Subject: Re: [docbook-apps] Syntax Highligher java.lang.StringIndexOutOfBoundsException: String index out of range: -1

Hello,

In a project I'm working on I hit the same StringIndexOutOfBoundsException.
I'm guessing the Xslthl parser really expects to see constructs that correspond to the language to highlight.

What was breaking in my document was:

<programlisting language="java">ldapport=1389</programlisting>

That's okay in a Java .properties file, so I thought it should be Java. But the Xslthl parser only processed it after I added a semicolon:

<programlisting language="java">ldapport=1389;</programlisting>

After I set language="ini" the first example worked.

It would be cool to see a line number or the string being processed when the exception gets thrown. Took a lot of time to find that missing semicolon.

Regards,
Mark

If I set the language to something unkown, e.g. "shell" then I do not get this error. I assume in this case the syntax highlighter is not called.

Hello,

I'm using the syntax highlighting as described here: http://www.sagehill.net/docbookxsl/SyntaxHighlighting.html

The default is set to Java. If I have the following construct I get an StringIndexOutOfBoundsException. Full stack trace below.

<para>
<programlisting>
&#xD;
telnet localhost 5554</programlisting>
</para>

Is this a bug?

Best regards, Lars
