Iterate through xml nodes within XSLT - xslt-1.0

Question

With in an xslt 1.0. I am calling a java function getTierByBundleId which returns below xml. I want to iterate through each Tier using for each. How can i do that
<xsl:variable name="varTierList" select="testclass:getTierByBundleId($bid,$ApplicationId)"/>
Xml returned by function getTierByBundleId
<TierList>
<Tier>
<TierId>1</TierId>
<Name>test</Name>
<Type>2</Type>
<Price>10</Price>
</Tier>
<Tier>
<TierId>2</TierId>
<Name>test</Name>
<Type>3</Type>
<Price>11</Price>
</Tier>
</TierList>
Here when I am trying to do xsl:for each on the variable which has the xml I am getting compilation error. How can I access each Tier from variable $varTierList
<xsl:for-each select="$varTierList/TierList/Tier">
<TierId><xsl:for each"Tierid"/>
</xsl:for-each
Below is the xslt which is generation the above TierList xml
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:foxtelclass="test.GetOrderQuote" exclude-result-prefixes="foxtelclass" extension-element-prefixes="testclass">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:if test="count(/ROWSET/ROW) > 0">
<TierList>
<xsl:for-each select="/ROWSET/ROW">
<Tier>
<TierId><xsl:value-of select="TIER_ID" /></TierId>
<Name><xsl:value-of select="NAME" /></Name>
<Type><xsl:value-of select="TIER_TYPE" /></Type>
<Price><xsl:value-of select="PRICE" /></Price>
</Tier>
</xsl:for-each>
</TierList>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
<xsl:for-each select="$varTierList/TierList/Tier"> is throwing the error message
Here is the full xslt

Below is the text from test node which what is xml variable varTierList contains
<test><TierList>
