Background image in XSL-FO from XML field

[francisco zenha]

Hi,

I need to have a background image to a table. That�s easy to do if we put the path on the url of the background image but my problem is that the path is on an XML field and i need to get it on the XSL-FO. How could i do this?

Thanks

I can imagine several possibilities, but since I don't exactly understand what you wrote there, could you post a small example of your input and your desired output? And an example of what you tried so far would help too.

I have this:
<fo:block-container width="20cm" height="21.6cm" background-image="image2.jpg">

what i want is that it gets the image2.jpg path from a field in the XML <image2>image2.jpg</image2> because this way i can change the path and name of the photo on the XML and never have to change the XSL file.

what i�ve tried was to include in the background-image an <fo:external-graphic> like this:

<fo:external-graphic>
<xsl:attribute name="src">
<xsl:text>url(</xsl:text>
<xsl:call-template name="double-backslash">
<xsl:with-param name="text">
<xsl:value-of select="string(image1)"/>
</xsl:with-param>
<xsl:with-param name="text-length">
<xsl:value-of select="string-length(string(image1))"/>
</xsl:with-param>
</xsl:call-template>
<xsl:text>)</xsl:text>
</xsl:attribute>
</fo:external-graphic>



I�ve tried to put this inside: <fo:block-container width="20cm" height="21.6cm" background-image="url(<fo:external-graphic>...)">

But these don�t work. Any idea?

Thanks

Well, that seems rather complicated to me. Why not just use an attribute-value template (AVT) to populate the background-image attribute, something like this:

<fo:block-container width="20cm" height="21.6cm" background-image="{image2}">

You'd put an XPath expression inside the {braces} which produces the required text as its result when coerced to a string.
