Here is what i tried
<xsl:import href="../resources/forms-samples-styling.xsl" />
<xsl:template match="*" mode="custom-styling">
<xsl:param name="required" />
<xsl:copy>
<xsl:if test="$required='true'">
<xsl:attribute name="class">required-field</xsl:attribute> <!-- (visual properties belong in CSS) -->
</xsl:if>
</xsl:copy>
</xsl:template>
<xsl:template match="fi:*" mode="common">
<!-- Apply the default transformation -->
<xsl:variable name="control">
<xsl:apply-imports/>
</xsl:variable>
<!-- Now apply our styling -->
<xsl:apply-templates select="exsl:node-set($control)" mode="custom-styling">
<xsl:with-param name="required" value="@required" />
</xsl:apply-templates>
</xsl:template>
notice the use of match="*" in the custom-styling template because i don't really know what's returned by exsl:node-set($control), but i guess it must be something like fi:* as not only the input control is concerned here, but also select, textarea, etc...
However, if i match
- "*" i get an empty <span class="forms-field-required"></span> after the control (the * is gone somewhere)
- "fi:*" i get the *, but not the <span> tag
and in both cases i don't get the class="required-field" attribute inserted on the control
I'm pretty new to xsl, so i'm not sure to understand the functioning of this, but i think if the template to be modified is the one spotted first (mode="styling", not mode="common"), maybe the second template should be <xsl:template match="fi:*" mode="styling">
However, if i try it, i get the <span class="forms-field-required">*</span> correctly, but the fi:styling of the control is lost (cols, lines....)
and i still don't get the class="required-field" attribute inserted on the control :-\
i'm a bit confused now...

The template for required is a different one:
<!--+ | Common stuff like fi:validation-message, @required. +--> <xsl:template match="fi:*" mode="common"> <!-- validation message --> <xsl:apply-templates select="fi:validation-message"/> <!-- required mark --> <xsl:if test="@required='true'"> <span class="forms-field-required"> * </span> </xsl:if> </xsl:template>
Nope, Marc got it right :-)... The mode="common" template generates the 'annotations', not the control itself.
does someone knows of a good technique to do this (if possible outside of forms-field-styling.xsl)
Write your own stylesheet, import forms-samples-styling.xsl into it and overload the template for the required attribute.
myforms.xsl:
<xsl:stylesheet>
<xsl:import href="forms-samples-styling.xsl"/>
<xsl:template match="fi:*" mode="common"> <!-- validation message --> <xsl:apply-templates select="fi:validation-message"/> <!-- required mark --> <xsl:if test="@required='true'"> <!-- something different here--> </xsl:if> </xsl:template>
</xsl:stylesheet>
Yes (except for being the wrong template... the mode="styling" one is correct).
And if copying the template seems undesirable, one might try injecting the attribute... something like:
<xsl:import href="forms-samples-styling.xsl" />
<xsl:template match="input" mode="custom-styling">
<xsl:param name="required" />
<xsl:copy>
<xsl:if test="$required='true'">
<xsl:attribute name="class">required-field</xsl:attribute> <!-- (visual properties belong in CSS) -->
</xsl:if>
</xsl:copy>
</xsl:template>
<xsl:template match="fi:*" mode="common">
<!-- Apply the default transformation -->
<xsl:variable name="control">
<xsl:apply-imports/>
</xsl:variable>
<!-- Now apply our styling -->
<xsl:apply-templates select="ex:node-set($control)" mode="custom-styling">
<xsl:with-param name="required" value="@required" />
</xsl:apply-templates>
</xsl:template>
You could enhance this to use different styling for a field that took a validation error (add a parameter to the custom-styling template)...
