I have observed an inconsistency in the escaping of characters while
migrating from a xalan-1 to xalan-2, 2.5.0. Here is a snippet of the
stylesheet:
<xsl:output method="html" indent="yes" doctype-public="-//W3C//DTD HTML
4.0 Transitional//EN"/>
...
<xsl:attribute name="href"><![CDATA[?NewPatient=true&PatientName
=]]><xsl:value-of disable-output-escaping="yes"
select="$PatientName"/><![CDATA[&UnitNum=]]><xsl:value-of
disable-output-escaping="yes"
select="$UnitNum"/><![CDATA[&MRNumber=]]><xsl:value-of
disable-output-escaping="yes"
select="$MRNumber"/><![CDATA[&Sex=]]><xsl:value-of
disable-output-escaping="yes"
select="$Sex"/><![CDATA[&BirthDate=]]><xsl:value-of
disable-output-escaping="yes"
select="$BirthDate"/><![CDATA[&RawDate=]]><xsl:value-of
disable-output-escaping="yes"
select="$RawDate"/><![CDATA[&DeathDate=]]><xsl:value-of
disable-output-escaping="yes"
select="$DeathDate"/>
in xalan-1 it produced the following html:
href="?NewPatient=true&PatientName=DOE,
JANE&UnitNum=10088&MRNumber=CC753422&Sex=F&BirthDate=
&RawDate=&DeathDate=
in xalan 2.5.0 it produced:
?NewPatient=true&PatientName=DOE,
JANE&UnitNum=10088&MRNumber=CC753422&Sex=F&BirthDate=&RawDate
=%C2%A0&DeathDate=%C2%A0
If I understand the stylesheet correctly; escaping should not occur at all
because of CDATA and disable-output-escaping. In xalan-1 escaping did
occur; but in xalan-2; it appears that it does not occur. Was this
something that was fixed or am I not understanding something? It looks like
I'll have to change this stylesheet to allow escaping to occur.
The dates are being selected as follows in the stylesheet:
<xsl:template name="DOB">
<xsl:param name="candidate"/>
<xsl:param name="raw" select="'false'"/>
<xsl:choose>
<xsl:when test="$raw!='true'">
<xsl:call-template name="DATE">
<xsl:with-param name="RawDate" select
="$candidate/memberInfo/dateOfBirth/birthDate"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select
="$candidate/memberInfo/dateOfBirth/birthDate"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template
The strange characters %C2%A0 are coming back when datOfBirth/birthDate or
dateOfDeath elements are not contained in the xml document being
transformed. Is this a bug?
Appreciate any ideas that may solve this issue.
