How do I check for the existence of an external file with XSL?
- by LOlliffe
I've found a lot of examples that reference Java and C for this, but how do I, or can I, check for the existence of an external file with XSL.
First, I realize that this is only a snippet, but it's part of a huge stylesheet, so I'm hoping it's enough to show my issue.
<!-- Use this template for Received SMSs -->
<xsl:template name="ReceivedSMS">
<!-- Set/Declare "SMSname" variable (local, evaluates per instance) -->
<xsl:variable name="SMSname">
<xsl:value-of select=" following-sibling::Name"/>
</xsl:variable>
<fo:table font-family="Arial Unicode MS" font-size="8pt" text-align="start">
<fo:table-column column-width=".75in"/>
<fo:table-column column-width="6.75in"/>
<fo:table-body>
<fo:table-row>
<!-- Cell contains "speakers" icon -->
<fo:table-cell display-align="after">
<fo:block text-align="start">
<fo:external-graphic src="../images/{$SMSname}.jpg" content-height="0.6in"/>
What I'd like to do, is put in an "if" statement, surronding the {$SMSname}.jpg line. That is:
<fo:block text-align="start">
<xsl:if test="exists( the external file {$SMSname}.jpg)">
<fo:external-graphic src="../images/{$SMSname}.jpg" content-height="0.6in"/>
</xsl:if>
<xsl:if test="not(exists( the external file {$SMSname}.jpg))">
<fo:external-graphic src="../images/unknown.jpg" content-height="0.6in"/>
</xsl:if>
</fo:block>
Because of "grouping", etc., I'm using XSLT 2.0. I hope that this is something that can be done. I hope even more that it's something simple.
As always, thanks in advance for any help.
