My input file is something like this

<DB>
<E>
<TAG1><![DATA[ "ep87" ]]></TAG1>
<TAG2><![DATA[ "0" ]]></TAG2>
<TAG3><![DATA[ "8.8.8.7" ]]></TAG3>
</E>
<E>
<TAG1><![DATA[ "EP7-1" ]]></TAG1>
<TAG2><![DATA[ "0" ]]></TAG2>
<TAG3><![DATA[ "192.168.5.1" ]]></TAG3>
</E>

</DB>

I want to able to search on string ep87 and get the output like

<E>
<TAG1><![DATA[ "ep87" ]]></TAG1>
<TAG2><![DATA[ "0" ]]></TAG2>
<TAG3><![DATA[ "8.8.8.7" ]]></TAG3>
</E>

You could do this with xslt:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml"/>

<xsl:param name="ep87" select="'ep87'"/>

<xsl:template match="text()"/>

<xsl:template match="TAG1[contains(., $ep87)]">
<xsl:copy-of select="parent::*"/>
</xsl:template>
</xsl:stylesheet>

most (all?) xslt tools will let you set a parameter from the command-line.
For instance, with xsltproc, you can run the above with

xsltproc --param ep87 "'EP7-1'" query.xsl data.xml
