Accessing an attribute from a nested tag XSLT

I need to access the attribute of a tag that exists several layers beneath the current tag.

For example: A snippet of the XML looks like this

<Content version="Title" action="add">
  <ProgramContent>
    <ContentMetaData>
      <ContentId>
        <HouseNumber>558960</HouseNumber>
        <AlternateId idType="SeriesId" authoritativeSource="BCM">19714</AlternateId>
        <AlternateId idType="EntityId" authoritativeSource="BCM">550133</AlternateId>
      </ContentId>
     </ContentMetaData>
   </ProgramContent>
</Content>

and my code currently looks like this:

<xsl:for-each select="ns0:BxfMessage/ns0:BxfData/ns0:Content">
   <xsl:if test="string(@version)= 'Title'">
     <xsl:if test="string(//AlternateId[@idType ='SeriesId'])">
       <test>hey</test>
     </xsl:if>
   </xsl:if>
</xsl:for-each>

I need to do a for-each loop on the content tag to check through all of them but then within that for-each loop I only want to continue operations if the attribute of the AlternateID tags doesn't contain seriesId. So if either of them are seriesId I want to end the if statement. How do I do this? As you can see I've tried an if statement that should check if the attribute idType is equal to SeriesId but it fails and doesn't return anything, am I doing something wrong?

Cheers

The function string() returns a string, but what you want is a Boolean. Something like test=//AlternateId[contains(@idType, 'SeriesId')] should work better.

So basically you want to loop over all <Content> elements that don't have a <AlternateID> element with the idType="SeriesId".

You can do that directly into the xsl:for-each like this:

<xsl:for-each select="ns0:BxfMessage/ns0:BxfData/ns0:Content[descendant::ns0:AlternateID/@idType != 'SeriesId']">
