XSLT if - attribute equal to string

Question

I use xsl:ifto fulfill a small condition in a larger block xsl:template, and I would like to check if the attribute of the current xsl:templatematching node is equal.

The following does not work:

<xsl:template match="sometag[@type='sometype']">
    ==Sometag==
    <xsl:if test="@something!='hidden'">something</xsl:if>
    <!--a lot of other stuff that I don't want to duplicate by multiplying the xsl:templates-->
<xsl:template>

This test seems to always evaluate to false, maybe I don't have a good syntax?

This XML:

<sometag type="sometype" something="visible"/>
<sometag type="sometype" something="hidden"/>
<sometag type="sometype"/>

Gotta give

==Sometag==
something...
==Sometag==
==Sometag==
something...

Answer 1

The 2nd tag should not print "something."

I'm not quite sure what you are trying to achieve, but I will try.

sometag something. @something!='hidden'. , "something" , something .

- , something , xsl:if.

<?xml version="1.0" encoding="utf-8"?>
<root>
<sometag type="sometype" something="visible"/>
<sometag type="sometype" something="hidden"/>
<sometag type="sometype"/>
</root>

Stylesheet

<?xml version="1.0" encoding="utf-8"?>

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

   <xsl:output method="text"/>
   <xsl:strip-space elements="*"/>

   <xsl:template match="/root">
      <xsl:apply-templates/>
   </xsl:template>

   <xsl:template match="sometag[@type='sometype']">
      <xsl:text>==Sometag==</xsl:text>
      <xsl:choose>
         <xsl:when test="@something">
            <xsl:if test="@something!='hidden'">
               <xsl:text>something</xsl:text>
            </xsl:if>
         </xsl:when>
         <xsl:otherwise>
            <xsl:text>something</xsl:text>
         </xsl:otherwise>
      </xsl:choose>
   </xsl:template>

</xsl:stylesheet>

EDIT @Tim C :

 <xsl:template match="sometag[@type='sometype']">
    <xsl:text>==Sometag==</xsl:text>
    <xsl:if test="@something!='hidden' or not(@something)">
       <xsl:text>something</xsl:text>
    </xsl:if>
 </xsl:template>

==Sometag==something==Sometag====Sometag==something

Answer 2

( @Mathias Müller , @Tim C), , or:

<xsl:template match="sometag[@type='sometype']">
    <xsl:text>==Sometag==</xsl:text>
    <xsl:if test="not(@something) or @something!='hidden'">
        <xsl:text>something</xsl:text>
    </xsl:if>
</xsl:template>

something , if true, @something!='hidden' .
