XSLT:How to deal with testing the value of an element? - xslt

Question

I have an xml file in which there is tag namely, <Gender/> It carries either 'M' or 'F' as data, now my work is to test the value and write <Gender_Tag>Male</Gender_Tag> or <Gender_Tag>Female</Gender_Tag> according to the values M or F respectively .. I tried this code .. It used to work in other circumstances..

Answer 1

All relative paths expressed in a template are evaluated against the current node. Your template match Gender elements, so Gender='M' returns true if there is any Gender's child named 'Gender' with the value 'M'. I guess this is not the case...
Use the dot to express the current node (here a Gender element):
<xsl:template match="root/details/Gender">
<Gender_Tag>
<xsl:choose>
<xsl:when test=".='M'">
<xsl:text>Male</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>Female</xsl:text>
</xsl:otherwise>
</xsl:choose>
</Gender_Tag>
</xsl:template>
EDIT: You may use two templates too
<xsl:template match="root/details/Gender[.='M']">
<Gender_Tag>Male</Gender_Tag>
</xsl:template>
<xsl:template match="root/details/Gender[.='F']">
<Gender_Tag>Female</Gender_Tag>
</xsl:template>

Answer 2

<xsl:template match="root/details/Gender">
<xsl:choose>
<xsl:when test="normalize-space(text())='M'">
<Gender_Tag>Male</Gender_Tag>
</xsl:when>
<xsl:otherwise>
<Gender_Tag>Female</Gender_Tag>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
My example differs in two points from Scoregraphic's:
It uses xsl:choose to ensure, that only one Gender_Tag element is created (that also means, that if the text is not 'M', it is always a Female)
Use of normalize-space() strips white space around the text content of the element.

Answer 3

Untested, but may work...
<xsl:template match="root/details/Gender">
<xsl:if test="text()='M'">
<Gender_Tag>Male</Gender_Tag>
</xsl:if>
<xsl:if test="text()='F'">
<Gender_Tag>Female</Gender_Tag>
</xsl:if>
</xsl:template>

Answer 4

Without seeing XML its hard to be certain, but I think your sample XSLT should be:
<xsl:template match="root/details/Gender">
<xsl:if test=".='M'">
<Gender_Tag><xsl:text>Male</xsl:text></Gender_Tag>
</xsl:if>
<xsl:if test=".='F'">
<Gender_Tag><xsl:text>Female</xsl:text></Gender_Tag>
</xsl:if>
</xsl:template>
Use of choose as per another answer would be better (though I think it should be two explicit when clauses rather than a when and an otherwise)
