Hi
I have a for-each loop
inside for-each I try to test a variable:

Sorry, I can't work out what your question is. Your code fragments below dont't have an xsl:if aand you gove no indication what you intend then to produce. (It is very hard to guess as they are so convoluted.

//if statement
  <xsl:if test="$foo = 1">
  //do nothing

  The varibale definition:
  	<xsl:variable name="foo"/>

That defines foo to be an empty string, butit doesn't matter what it defines it to be as you immediately discard this variable and over-write it with another one with the same name:

  		<xsl:variable name="foo">
					<xsl:for-each select="data">
						<xsl:choose>
							<xsl:when test="contains(elements/elementA '1234)">

								<xsl:value-of select="1"/>
							</xsl:when>
							<xsl:otherwise>
								<xsl:value-of select="0"/>
							</xsl:otherwise>
						</xsl:choose>
					</xsl:for-each>
				</xsl:variable>
				

that defines $foo to be a document node with a sing;e text node child that is a sequence of 1s and 0s.

				
				
Unfortunatelly the value of the varable foo is either 001 , 011,00011 and so one

That is what I'd expect, but yu don't say what you want it to be.


and the if statement works never correct !

There is no if?

I even defined the varable as a xs:integer type or as below , but ever the value is never a 1 or 0

<xsl:variable name="foo"  select='1'"/>
  		<xsl:variable name="foo">
					<xsl:for-each select="data">
						<xsl:choose>
							<xsl:when test="contains(elements/elementA, '1234)">

								<xsl:value-of select="'1'"/>
							</xsl:when>
							<xsl:otherwise>
								<xsl:value-of select="'0'"/>
							</xsl:otherwise>
						</xsl:choose>
					</xsl:for-each>
				</xsl:variable>
