FW: Using a processing instruction to remove a node

I have an XML document with a processing instruction that precedes a
node that I'd like removed, but I'm having trouble with the XSL. Any
help would be appreciated. Thanks.

Here's an example of the XML document.
<?xml version="1.0" encoding="UTF-8"?>
<root>
	<node value="1">
		<inner-node>1</inner-node>
	</node>
	<?REMOVE?>
	<node value="2">
		<inner-node>2 - remove me</inner-node>
	</node>
	<node2 value="3">
		<inner-node>3</inner-node>
	</node2>
	<node2 value="4">
		<inner-node>4</inner-node>
	</node2>
</root>

This is the result I want.
<?xml version="1.0" encoding="UTF-8"?>
<root>
	<node value="1">
		<inner-node>1</inner-node>
	</node>
	<node2 value="3">
		<inner-node>3</inner-node>
	</node2>
	<node2 value="4">
		<inner-node>4</inner-node>
	</node2>
</root>

Here's the XSL I have currently.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8"/>
<xsl:template match="node()">
	<xsl:copy>
		<xsl:copy-of select="@*"/>
		<xsl:apply-templates
select="node()[not(preceding-sibling::processing-instruction('REMOVE'))]
"/>
	</xsl:copy>
</xsl:template>
<xsl:template match="processing-instruction('REMOVE')">
</xsl:template>
</xsl:stylesheet>

Here's the result that I'm getting.
<?xml version="1.0" encoding="UTF-8"?>
<root>
	<node value="1">
		<inner-node>1</inner-node>
	</node>
</root>
