RE: HTML characters being converted

[David Lamy <DLamy@xxxxxxxxxxx>]

Thanks for the responses.  Here's some XML/XSL code.  Please be gentle..
I'm suddenly feeling much more self-conscious about my XSL ;-).

XML: (important elements here are the CheckBoxGroup and the CheckBox)
		<CheckBoxGroup numberOfColumns="2">
			<CheckBox checked="true">
				<CheckBoxValueDataSource>
					<TextData>1</TextData>
				</CheckBoxValueDataSource>
				<CheckBoxDisplayDataSource>
					<TextData>checked by
default</TextData>
				</CheckBoxDisplayDataSource>
			</CheckBox>
			<CheckBox>
				<CheckBoxValueDataSource>
					<TextData>2</TextData>
				</CheckBoxValueDataSource>
				<CheckBoxDisplayDataSource>
					<TextData>another choice to
select</TextData>
				</CheckBoxDisplayDataSource>
			</CheckBox>
			<CheckBox>
				<CheckBoxValueDataSource>
					<TextData>3</TextData>
				</CheckBoxValueDataSource>
				<CheckBoxDisplayDataSource>
					<TextData>check this one
too</TextData>
				</CheckBoxDisplayDataSource>
			</CheckBox>
			<CheckBox>
				<CheckBoxValueDataSource>
					<TextData>4</TextData>
				</CheckBoxValueDataSource>
				<CheckBoxDisplayDataSource>
					<TextData>not me though
</TextData>
				</CheckBoxDisplayDataSource>
			</CheckBox>
		</CheckBoxGroup>
<!--END OF XML-->

XSL: (please note that this stuff is pretty screwed up right now.. a)
I'm using the shortcut LotusXSL java object tagging and b) the script is
pretty screwy, probably due to a concussion from my repeated
head-banging :-).  My efforts with the java code was to hide the <tr>
tags from the XSL so it wouldn't complain.  It works, but with the &lt;
problem described earlier.  The start() method simply spits out a <tr>.
The nextElement() method spits out a </tr><tr> IF the number of columns
specified in the CheckBoxGroup attribute has been reached.  The
remainder() method will spit out <td>&nbsp;</td> for each remainder
column.. ie if numberOfColumns = 2 and there are 7 checkboxes, then one
<td>&nbsp;</td> will be spit so that table integrity is kept.  The
with-param is used so that the ID of the checkbox assumes the ID of the
CheckBoxGroup so that all of the CheckBoxes in the group assume the same
HTML identity for CGI purposes.  A CheckBox can exist outside of a group
so if no param is passed in it will keep the original ID given it (I've
left out the ID stuff in the XML but trust me, it's there.

	<xsl:template match="CheckBoxGroup">
		<table> 
			<xsl:variable name="groupCols"
select="java:com.marketv.three60.server.xml.XslGroupColumn.new()"/>
			<xsl:variable name="numCols"
select="./@numberOfColumns/text()"/>
			<xsl:if test="java:setColSize($groupCols,
$numCols)" />
			<xsl:variable name="start"
select="java:start($groupCols)"/>
			<xsl:copy-of select="$start"/>
			<xsl:for-each select="CheckBox">
				<td>
					<xsl:apply-templates select=".">
						<xsl:with-param
name="ID" select="../../@id"/>
					</xsl:apply-templates>
				</td>
				<xsl:copy-of
select="java:nextElement($groupCols)"/>
			</xsl:for-each>
			<xsl:copy-of
select="java:remainder($groupCols)"/>
		</table>
	</xsl:template>
	<xsl:template match="CheckBox">
		<xsl:param name="ID" select="../@id"/>
		<xsl:choose>
			<xsl:when test="./@checked = 'true'">
				<input type="checkbox" checked=""
name="{$ID}" value="{./CheckBoxValueDataSource/TextData/text()}">
					<xsl:value-of
select="./CheckBoxDisplayDataSource/TextData/text()"/>
				</input>
			</xsl:when>
			<xsl:otherwise>
				<input type="checkbox" name="{$ID}"
value="{./CheckBoxValueDataSource/TextData/text()}">
					<xsl:value-of
select="./CheckBoxDisplayDataSource/TextData/text()"/>
				</input>
			</xsl:otherwise>
		</xsl:choose>
	</xsl:template>

Please feel free to rip this apart.. I'm prepared for an educational
session here so that I can be the best XSL author I can possibly be :-).
And thanks again for all of your help.
