xslt cannot assign a param with a boolean value within `<xsl:choose>`
this code is giving me the output test when the expected output should be nothing..
Is it something wrong with my XSLT processor or..? :
<xsl:template match="/">
<xsl:param name="IsTextArea">
<xsl:choose>
<xsl:when test="false()">
<xsl:value-of select="true()"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="false()"/>开发者_如何学JAVA
</xsl:otherwise>
</xsl:choose>
</xsl:param>
<html>
<xsl:choose>
<xsl:when test="$IsTextArea">test
</xsl:when>
</xsl:choose>
</html>
</xsl:template>
Btw i need a solution for raw XSLT 1.0 (no extensions and stuff like that).
Is it possible to set a boolean parameter for a param in XSLT 1.0?
Your parameter is evaluating to a string. You should use:
<html>
<xsl:choose>
<xsl:when test="$IsTextArea = 'true'">
test
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$IsTextArea"/>
</xsl:otherwise>
</xsl:choose>
</html>
The xsl:value-of instruction converts whatever you give it to a string. So true() becomes "true", and false() becomes "false". When you use a string in a boolean context, any non-empty string becomes true(), while "" becomes false(). So boolean->string->boolean conversion doesn't round-trip. In XSLT 2.0 the answer is to use xsl:sequence instead of xsl:value-of; in 1.0, just use strings like "yes" and "no" to avoid confusion.
Shouldn't it be like this:
<xsl:param name="IsTextArea">
<xsl:choose>
<xsl:when test="false()">
<xsl:value-of select="false()"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="true()"/>
</xsl:otherwise>
</xsl:choose>
Are think your true and false were out of place.
