In order to select all node, try xslt transformation:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text" indent="yes"/> <xsl:template match="node()"> <xsl:value-of select="." /> </xsl:template> </xsl:stylesheet> 

This will output content of all node in your xml file.
