xslt param conditional check
I have a:
<xsl:param name="SomeFlag" />
In my XSLT template, I want to do a conditional check on SomeFlag. Currently I'm doing it as:
<xsl:if test="$SomeFlag = true"> SomeFlag is true! </xsl:if>
Is this how we evaluate the the flag?
I'm 开发者_运维问答setting the param in C# as:
xslarg.AddParam("SomeFlag", String.Empty, true);
Any ideas?
<xsl:if test="$SomeFlag = true">
This tests if $SomeFlag
is equal to the string value of the element named "true", which is the first child of the current node.
What you want is:
<xsl:if test="$SomeFlag = true()">
I agree with Dimitre, but have an addition:
In your case you can just use:
<xsl:if test="$SomeFlag"> SomeFlag is true! </xsl:if>
But I usually use 1 and 0 for boolean flags when the flags are supposed to be evaluated in XSLT, especially when I take the value from an attribute or an element content.
This allow me to test conditions by casting to numbers (and then implicitly to boolean) instead of comparison to a string literal:
<xsl:if test="number($SomeFlag)"> SomeFlag is true! </xsl:if>
