Re: loop timing and result-document flush

XSL experts,

I have an XSL which loops over a set of elements in search of links and creates a result document for the link. In some cases there is more than one link to the same anticipated document, so I use the doc-available() to test first for its existence before creating the file.

This is intended to avoid a DynamicError related to writing more than one result document to the same URI.

BUILD FAILED
/Users/dgran/dev/rose/build.xml:395: The following error occurred while executing this line:
/Users/dgran/dev/rose/build.xml:77: net.sf.saxon.trans.DynamicError: Cannot write more than one result document to the same URI: file:/Users/dgran/dev/rose/build/zoom/1-1861.wrenn.320-321.img.html

In the first case, the file (1-1861.wrenn.320-321.img.html) is correctly created because it doesn't exist yet. In the second case the doc-available() method should return true

and skip the result-document command, but it fails to work. My hypothesis is that the result-document() method isn't finished flushing before the call to doc-available() is made.

Assuming my guess is correct, is there a way in XSL to assure that the document is finished writing before continuing to the next iteration in the loop?

Maybe there is another way of skinning this cat.

I welcome suggestions. I'm using Saxon 8-7-3j. Below is a simplified version of my stylesheet:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:template match="/">
<xsl:for-each select="ram|//repro|//page|//figure">

<xsl:variable name="zoomhtml">
<xsl:text>build/zoom/</xsl:text>
<xsl:value-of select="@image"/>
<xsl:text>.img.html</xsl:text>
</xsl:variable>
<xsl:message>
test for doc <xsl:value-of select="$zoomhtml"/> available: <xsl:value-of select="doc-available($zoomhtml)"/>

      </xsl:message>
      <xsl:choose>
        <xsl:when test="doc-available($zoomhtml)"/>
