Hi,
 I am looking to compress a particular node in an XML. Other parts of the XML need to be unaltered and I am getting all the XML within the node in a string, using zlib to compress the string, and adding the compressed string to the node again. But when I try to load this compressed XML in to the DOM again it complains about invalid characters in input. Has someone ever done this or is there a proper solution to this? Thanks in advance.

Sam.

You need to save the resulting compressed stream within a CDATA section so the XML parser ignores it.

<compressedNode>
   <![CDATA[compressed data goes here]]>
</compressedNode>

Take a look at this article for more details.

Thanks Peter. Actually I hadn't mentioned that the characters, after compression are looking obscure and I don't know how to handle those. (something like this: ÝZ¥ïa®÷YLœãPŸèT¢îOê etc.) The whole XML is enclosed within a CDATA and still the DOM complains. Any ideas?
