Re: Conditional Assigining

Here comes my XML FILE
<xslTutorial >

<section>
<sectionID>1</sectionID>
<parentID>0</parentID>
<text>section 1</text>
</section>

<section>
<sectionID>2</sectionID>
<parentID>0</parentID>
<text>section 2</text>
</section>

<section>
<sectionID>3</sectionID>
<parentID>1</parentID>
<text>section 1.1</text>
</section>

<section>
<sectionID>4</sectionID>
<parentID>1</parentID>
<text>section 1.2</text>
</section>

<section>
<sectionID>5</sectionID>
<parentID>3</parentID>
<text>section 1.1</text>
</section>

<section>
<sectionID>6</sectionID>
<parentID>2</parentID>
<text>section 2.1</text>
</section>

<section>
<sectionID>7</sectionID>
<parentID>2</parentID>
<text>section 2.2</text>
</section>

<section>
<sectionID>8</sectionID>
<parentID>6</parentID>
<text>section 2.1.1</text>
</section>
</xslTutorial>

My xsl file read as follows:
-----------------------------
<xsl:template match="First">
	<xsl:for-each select="Section[parentID='0']">
		<xsl:variable name="ID" select="sectionID"/>
		<xsl:call-template name="recur">
			<xsl:with-param name="id">
				<xsl:value-of select="sectionID" />
			</xsl:with-param>
			<xsl:with-param name="pid">
				<xsl:value-of select="parentID" />
			</xsl:with-param>
			<xsl:with-param name="textvalue">
				<xsl:value-of select="text" />
			</xsl:with-param>
		</xsl:call-template>
		<xsl:for-each select="../Section[parentID=$ID]">
		sub
			<xsl:variable name="ID" select="sectionID"/>
			<xsl:call-template name="recur">
				<xsl:with-param name="id">
					<xsl:value-of select="sectionID" />
				</xsl:with-param>
				<xsl:with-param name="pid">
					<xsl:value-of select="parentID" />
				</xsl:with-param>
				<xsl:with-param name="textvalue">
					<xsl:value-of select="text" />
				</xsl:with-param>
			</xsl:call-template>
			<xsl:apply-templates select="child::*/section" />
			<xsl:text>
			</xsl:text>
		</xsl:for-each>
		<!--after functiion
		<xsl:call-template name="recur">
				<xsl:with-param name="id">
					<xsl:value-of select="sectionID" />
				</xsl:with-param>
				<xsl:with-param name="pid">
					<xsl:value-of select="parentID" />
				</xsl:with-param>
				<xsl:with-param name="textvalue">
					<xsl:value-of select="text" />
				</xsl:with-param>
			</xsl:call-template>-->
		</xsl:for-each>

<xsl:template name="recur">
	<xsl:param name="id" />
	id <xsl:value-of select="$id"/>
	<xsl:param name="pid" />
	pid <xsl:value-of select="$pid"/>
	<xsl:param name="textvalue" />
	text <xsl:value-of select="$textvalue"/>

</xsl:template>
<xsl:template name="recur1">
	<xsl:param name="id" />
	id <xsl:value-of select="$id"/>
	<xsl:param name="pid" />
	pid <xsl:value-of select="$pid"/>
	<xsl:param name="textvalue" />
	text <xsl:value-of select="$textvalue"/>

My output is as follows:
---------------------------
<?xml version="1.0" encoding="UTF-8"?>

	id 1
	pid 0
	text Section 1
		sub

	id 5
	pid 1
	text Section 1.1

	id 2
	pid 0
	text Section 2
		sub

	id 6
	pid 2
	text Section 2.1

	id 6
	pid 2
	text Section 2.1.1

Hi Sri,

> <xsl:variable name="ID">-1</xsl:variable>
> <xsl:for-each select="Section[parentID='0']">
>         <xsl:if test="$ID=-1">
>                 <xsl:variable name="ID" select="sectionID" />
>         </xsl:if>
> id <xsl:value-of select="$ID"/>

You cannot use variables in this way within XSLT. A variable's scope
is limited to its following siblings and their descendants, and you
cannot reassign a different value to the variable (unless you use an
extension element like saxon:assign).

If you want to get the value of the sectionID of that first Section
element, then that's what you should set the value of the variable to:

<xsl:variable name="ID" select="Section[parentID = '0'][1]" />

I hope that helps,

Jeni
