Get next tag name with position in XSL

I want to check if the next parent is test or foo using position(.)+1 (that's the idea).

XML:

<text>
   <list>
      in list
   </list>
   <table>
      I'M HERE
   </table>
</text>
<foo>
   <hey>
   </hey>
</foo>

Can I do something like that ?

XSL :

<xsl:if test="position(.)+1 = 'foo'">
  <xsl:value-of select="'Next tag is foo'" />
</xsl:if>

And I want to know if I can put 2 conditions in <xsl:if> like :

My output is in html.

Edit : wrong question.

You have changed your question significantly. First you wanted the first child, now the following sibling, will answer both cases, first the explanation of the above terms:

<text>
  <table></table>    <-- first child       (nested one level)
</text>
<foo />              <-- following sibling (same hierarchy level)

Check if the first child of <text> is <list> or <table>

The query you are looking for is:

<xsl:if test="name(*[1]) = 'list' or name(*[1]) = 'table'">

Full example:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/text">
        <xsl:if test="name(*[1]) = 'list' or name(*[1]) = 'table'">
            <xsl:text>first child of text node is list or table</xsl:text>
        </xsl:if>
    </xsl:template>
</xsl:stylesheet>

Check if the following sibling of <text> is <list> or <table>

The query you are looking for is:

<xsl:if test="name(following-sibling::*[1]) = 'list' or name(following-sibling::*[1]) = 'table'">

Full example:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/text">
        <xsl:if test="name(following-sibling::*[1]) = 'list' or name(following-sibling::*[1]) = 'table'">
            <xsl:text>following sibling of text node is list or table</xsl:text>
        </xsl:if>
    </xsl:template>
</xsl:stylesheet>

Almost.

  1. Use the following-sibling axis to get the next element (following-sibling::*[1]) [*]
  2. Use the self axis to check if that element itself is a <list> ([self::list])

e.g. [+]

<xsl:if test="following-sibling::*[1][self::list]">
  <xsl:value-of select="'Next tag is list'" />
</xsl:if>

[*] following-sibling::* selects all following siblings, you want only the first one, hence the [1].

[+] Multiple predicates (sub-expressions in square brackets) must be true in succession. This means the XPath expression either selects a non-empty node set (which evaluates to true in a Boolean test) or it selects the empty node-set (which evaluates to false). There is no need for an explicit comparison here.
