Henry Zongaro updated XALANJ-1931:
----------------------------------
Priority: Major
> XSL-T Stylesheet Succeeds With Small Stream, Fails With Large
> -------------------------------------------------------------
>
> Key: XALANJ-1931
> URL: http://nagoya.apache.org/jira/browse/XALANJ-1931
> Project: XalanJ2
> Type: Bug
> Components: transformation, Xalan-interpretive
> Versions: 2.6
> Environment: Operating System: Windows NT/2K
> Platform: PC
> Reporter: Michael O. Duffy
> Assignee: Xalan Developers Mailing List
>
> I wrote a simple XSL-T stylesheet to make the following change to an XML
> stream:
> "Copy out the input stream elements into the output stream. If you find a
> <queryItem> whose <datatype> child has the value 'character', add the
> following
> element after the <nullable> child:
> <promptInfo>
> <promptType>selectWithSearch</promptType>
> </promptInfo>
> "
> This is the stylesheet that I wrote:
> <!--
> A simple stylesheet for adding a tag to a document
> -->
> <xsl:stylesheet version="1.0"
> xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
> <!-- Copy the document in its entirety -->
> <xsl:template match="*|@*|comment()|processing-instruction()|text()">
> <xsl:copy>
> <xsl:apply-templates
> select="*|@*|comment()|processing-instruction()
> |text()"/>
> </xsl:copy>
> </xsl:template>
>
>
> <!-- Find the queryItem tag and add a promptInfo child after nulllable
> for
> character datatype-->
> <xsl:template match="queryItem">
> <queryItem>
> <xsl:apply-templates select="name"/>
> <xsl:apply-templates select="lastChanged"/>
> <xsl:apply-templates select="columnName"/>
> <xsl:apply-templates select="usage"/>
> <xsl:apply-templates select="datatype"/>
> <xsl:apply-templates select="precision"/>
> <xsl:apply-templates select="scale"/>
> <xsl:apply-templates select="size"/>
> <xsl:apply-templates select="nullable"/>
> <xsl:if test="datatype/text()='character'">
> <promptInfo>
> <promptType>selectWithSearch</promptType>
> </promptInfo>
> </xsl:if>
> <xsl:apply-templates select="regularAggregate"/>
> <xsl:apply-templates select="semiAggregate"/>
> </queryItem>
> </xsl:template>
> </xsl:stylesheet>
> I apply it to this simple XML stream:
> <?xml version="1.0" encoding="UTF-8"?>
> <project>
> <name>KMC Master Model</name>
> <locales>
> <locale>en-US</locale>

> The output is as expected (<promptType> child not added for the first
> <queryItem>; added for the second one):

> However, when I apply the identical transformation to a larger stream
> (3.7MB),
> which was the source of the <queryItem> instances used in the small test
> stream, I find that the original stream is copied out, and NO <promptType>
> children are added. No exceptions were thrown.
> I used -Xmx128m as an argument when I ran xalan.jar, without effect. Why
> would
> a transformation succeed on a smaller XML input stream and fail on a larger
> one?
