Hi,

I have RGB value's in my XML file, they look like this:


<egInk:r>.3218039274</egInk:r>

<egInk:g>.4258823395</egInk:g>

<egInk:b>.4894117713</egInk:b>

I want a square in my html file with those RGB value's as color.
I've tried this:

Code: Select all


<div class="kleurvak" style="background-color:rgb(<xsl:value-of select="round(egInk:r*256)"/>,<xsl:value-of select="round(egInk:g*256)"/>,<xsl:value-of select="round(egInk:b*256)"/>);">



</div>

But I can't put an xslt element in an attribute of a div element.
Is there an other way to do this?

Hello,

There are two ways to obtain what you want.
Instead of directly declaring the "div" element and its attributes in the stylesheet, you can generate them using the xsl:element and xsl:attribute elements (http://www.w3.org/TR/xslt#section-Creat ... sl:element). Here is an example of how you can do this:

Code: Select all


    <xsl:element name="div">

        <xsl:attribute name="class">kleurvak</xsl:attribute>

        <xsl:attribute name="style">

            <xsl:text>background-color:rgb(</xsl:text>

            <xsl:value-of select="round(egInk:r*256)"/>

            <xsl:text> , </xsl:text>

            <xsl:value-of select="round(egInk:g*256)"/>

            <xsl:text> , </xsl:text>

            <xsl:value-of select="round(egInk:b*256)"/>

            <xsl:text>)</xsl:text>

        </xsl:attribute>

    </xsl:element>

Another way to obtain the result is by using the attribute value templates feature of XSLT (http://www.w3.org/TR/xslt#attribute-value-templates). This means you can use an xpath expression inside an attribute value by surrounding it with curly braces ({}). In your case it will look something like this:

Code: Select all


    <div class="kleurvak" style="background-      color:rgb({round(egInk:r*256)},{round(egInk:g*256)},{round(egInk:b*256)})">

    </div>

Let us know if you have further questions regarding this issue.
