Xsl Nested Loop

I am trying to display a subset of data that matches based on the ExchangeWantedId.  How do I set this up?  Here is what I have thus far:

Here is the XML

<xs:element name="ExchangeWantedItemsMeToodUsers">
<xs:complexType>
- <xs:sequence>
  <xs:element name="ExchangeWantedId" type="xs:int" minOccurs="0" />
  <xs:element name="ExchangeWantedName" type="xs:string" minOccurs="0" />
  <xs:element name="MeTooer" type="xs:string" minOccurs="0" />
  <xs:element name="MeTooerBankName" type="xs:string" minOccurs="0" />
  <xs:element name="DateFulfilled" type="xs:string" minOccurs="0" />
  <xs:element name="DateFulfilledUnformated" type="xs:dateTime" minOccurs="0" />
  <xs:element name="UserID" type="xs:int" minOccurs="0" />
  <xs:element name="FullName" type="xs:string" minOccurs="0" />
  <xs:element name="PostedBankName" type="xs:string" minOccurs="0" />
  </xs:sequence>
  </xs:complexType>
  </xs:element>
- <xs:element name="ExchangeWantedItemsMeToodUsers1">
- <xs:complexType>
- <xs:sequence>
  <xs:element name="ExchangeWantedID" type="xs:int" minOccurs="0" />
  <xs:element name="DisplayName" type="xs:string" minOccurs="0" />
  <xs:element name="FullName" type="xs:string" minOccurs="0" />
  </xs:sequence>
  </xs:complexType>
  </xs:element>
Here is the xsl

<xsl:for-each select="/root/ExchangeWantedItemsMeToodUsers">                
    <tr>
        <xsl:call-template name="AlternateRowColor" />
        <td><xsl:value-of select="ExchangeWantedName" /></td>
        <td>
            <xsl:for-each select="/root/ExchangeWantedItemsMeToodUsers">
                <xsl:value-of select="MeTooer" /> - <xsl:value-of
                                                    select="MeTooerBankName" />
            </xsl:for-each>
        </td>
        <td><xsl:value-of select="FullName" /> - <xsl:value-of
                                                select="PostedBankName" /></td>
        <td><xsl:value-of select="DateFulfilled" /></td>
    </tr>
</xsl:for-each>

For being selective you could use predicates []
<xsl:for-each select="/root/ExchangeWantedItemsMeToodUsers">
could be something like this
<xsl:for-each select="/root/ExchangeWantedItemsMeToodUsers[ExchangeWantedId = $your-value]">

where $your-value is a variable you gave the test value earlier

or directly if you need that
<xsl:for-each select="/root/ExchangeWantedItemsMeToodUsers[ExchangeWantedId = 'foo']">

It strikes me that you have another loop inside your for-each, and that you also start from the root there
Please note that you have everything in context inside the loop
please explain what you want to achieve, with input and output document atteched, so I can help

https:#a34931805 contains an general good advice above selectivity in apply templates / for-each AND it contains an important suggestion about inner context of a for-each loop, something a lot of XSLT beginners struggle with

Please accept that comment as an answer
