multiple line in headers..

hi..

have read your reply, about column ids, and worked great..

i have another question though..
i've been trying to make multiple line in headers via the xml file..

ive tried these..
1.
<column>hi<br>hello
</column>

2.
<column>hi \n hello
</column>

3.
<column>hi
hello
</column>

i wanted to place them in the header as: hi
hello

but none work..

and another thing..
i have a java code that tokenizes a very long string, and every token i get i write in the xml, the problem is some of the tokens
has an aphostrophe ( ' ), which i think causes the error in xml..the error message is "Invalid byte 1 of 1-byte UTF-8 sequence.".
this causes the xml to be invalid input for the grid..



thank you so much for the help..you've been very helpful..

>>i've been trying to make multiple line in headers via the xml file.

One of correct solutions

<column><![CDATA[ hi<br>hello  ]]></column>

or

<column>hi &lt;br&gt; hello</column>

You can use any html tags inside header, but they must be escaped in one or another way.

>>the error message is "Invalid byte 1 of 1-byte UTF-8 sequence

The data which you process stored as UTF string, or as string in some other encoding ?
If you process and output data in non-utf encoding you must specify it in XML header

<? xml version="1.0" encoding="iso-8859-1" ?> // this is western european encoding

in common case the data can be safely escaped as
<cell><![CDATA[  anything here  ]]></cell>
but in you case I think problem is in encoding.
