gather and concatinate data

[CassidyHunt]

Is there a way in XSL to do this:

dim str as string
dim i as integer

for i = 0 to 10
   str = str & i & ";"
next

What my situation is I am running through a loop of data that I need to gather into one variable and print in a hidden element on a webpage. Then I will take my javascript and analyze it in an array.

I guess what I am lacking is to be able to modify a variable and keep the existing data stored in it.

Thanks

Cassidy

Not sure... maybe this will do for you?

<!-- [blue]or some template of some match so select for str make more definitive meaning[/blue] -->
<xsl:template match="/">
[blue]<xsl:variable name="str" select="'abcde'" />[/blue]
<xsl:variable name="str_sffx">
<xsl:call-template name="base">
<xsl:with-param name="n" select="10" />
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="concat($str,$str_sffx)" />
</xsl:template>

<xsl:template name="base">
<xslaram name="s" />
<xslaram name="n" />
<xsl:if test="$n &gt;= 0">
<xsl:call-template name="callee">
<xsl:with-param name="m" select="$n" />
</xsl:call-template>
<xsl:value-of select="concat($n,';')" />
</xsl:if>
</xsl:template>

<xsl:template name="callee">
<xslaram name="m" />
<xsl:call-template name="base">
<xsl:with-param name="n" select="$m - 1" />
</xsl:call-template>
</xsl:template>

Cassidy,

As always, an example of the input (probably simplified, but still showing the basic input structure) and the desired output would probably get a better answer.

My guess is that you can accomplish what you want to do in an xsl:for-each construct, inside an xsl:attribute, but I need to see the actual problem first.

Tom is right, there's probably a more elegant solution if the problem is better defined. For your general question though, iteration can only be done through recursion as in tsuji's post or below (although you could use tokenise function in XPath 2 or extensions).

<xsl:template match="/">
  <xsl:call-template name="iterate">
    <xsl:with-param name="end" select="10"/>
  </xsl:call-template>
</xsl:template>

<xsl:template name="iterate">
  <xsl:param name="i"/>
  <xsl:param name="end"/>
  <xsl:value-of select="concat($i, ';')" />
  <xsl:if test="$i &lt; $end">
    <xsl:call-template name="iterate">
      <xsl:with-param name="i" select="$i + 1" />
      <xsl:with-param name="end" select="10"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>
