xmlrpc.php striping html

Hello
I have 2 programs
(Blog Post Builder) & (Qumana Blog Manager)
and its uses the xmlrpc.php
everything seems to go well but when it submits to my blog
it seems to strip out the Angle brackets Ex: (<)(</)(>)
I have disabled the Visual Editor
and am running WP 2.7

I have looked at the code
and found this does it have anything to do with it
and if so how can I stop it from doing this?

// Work around bug in strip_tags():
		$linea = str_replace('<!DOC', '<DOC', $linea);
		$linea = preg_replace( '/[\s\r\n\t]+/', ' ', $linea ); // normalize spaces
		$linea = preg_replace( "/ <(h1|h2|h3|h4|h5|h6|p|th|td|li|dt|dd|pre|caption|input|textarea|button|body)[^>]*>/", "\n\n", $linea );

		preg_match('|<title>([^<]*?)</title>|is', $linea, $matchtitle);
		$title = $matchtitle[1];
		if ( empty( $title ) )
			return new IXR_Error(32, __('We cannot find a title on that page.'));

		$linea = strip_tags( $linea, '<a>' ); // just keep the tag we need

		$p = explode( "\n\n", $linea );

		$preg_target = preg_quote($pagelinkedto);

		foreach ( $p as $para ) {
			if ( strpos($para, $pagelinkedto) !== false ) { // it exists, but is it a link?
				preg_match("|[^>]+?".$preg_target."[^>]*>([^>]+?)|", $para, $context);

				// If the URL isn't in a link context, keep looking
				if ( empty($context) )
					continue;

				// We're going to use this fake tag to mark the context in a bit
				// the marker is needed in case the link text appears more than once in the paragraph
				$excerpt = preg_replace('|\</?wpcontext\>|', '', $para);

				// prevent really long link text
				if ( strlen($context[1]) > 100 )
					$context[1] = substr($context[1], 0, 100) . '...';

				$marker = '<wpcontext>'.$context[1].'</wpcontext>';    // set up our marker
				$excerpt= str_replace($context[0], $marker, $excerpt); // swap out the link for our marker
				$excerpt = strip_tags($excerpt, '<wpcontext>');        // strip all tags but our context marker
				$excerpt = trim($excerpt);
				$preg_marker = preg_quote($marker);
				$excerpt = preg_replace("|.*?\s(.{0,100}$preg_marker.{0,100})\s.*|s", '$1', $excerpt);
				$excerpt = strip_tags($excerpt); // YES, again, to remove the marker wrapper
				break;
			}
		}

		if ( empty($context) ) // Link to target not found
			return new IXR_Error(17, __('The source URL does not contain a link to the target URL, and so cannot be used as a source.'));

		$pagelinkedfrom = str_replace('&', '&amp;', $pagelinkedfrom);

		$context = '[...] ' . wp_specialchars( $excerpt ) . ' [...]';
		$pagelinkedfrom = $wpdb->escape( $pagelinkedfrom );
