Set input value from substring - xslt

Question

here is my xsl (xslt 1.0)
<tr>
<td align="center" height="60">
<input type="hidden" id="imageA" value="{Item}"/>
<div id="barcode" class="barcode"></div>
</td>
</tr>
The value="{Item}" is a string.
item1;item2;item3;item4;
How to get the 'item3' only?
This will be passed into JavaScript to generate barcode. Currently the barcode is able to show for simple string.

Answer 1

You can use:
substring-before(substring-after(substring-after(Item, ';'), ';'), ';')
to extract the third value of a semicolon separated string.
Alternatively, if using the Xalan-J processor (or another processor supporting the EXSLT str:tokenize() function):
str:tokenize(Item, ';')[3]

Answer 2

XSLT 1.0 allows only immutable variables. You can use recursion on a variable that contains the data of your "value" attribute.
<xsl:template match="/*">
<root>
<xsl:variable name="data" select="td/input/#value"/>
<xsl:call-template name="find">
<xsl:with-param name="count" select="1"/>
<xsl:with-param name="data" select="substring-after($data,';')"/>
<xsl:with-param name="prevData" select="substring-before($data,';')"/>
</xsl:call-template>
</root>
</xsl:template>
<xsl:template name="find">
<xsl:param name="count"/>
<xsl:param name="data"/>
<xsl:param name="prevData"/>
<xsl:if test="$count=3">
<data>
<xsl:value-of select="$prevData"/>
</data>
</xsl:if>
<xsl:if test="$count < 3">
<xsl:call-template name="find">
<xsl:with-param name="count" select="$count+1"/>
<xsl:with-param name="data" select="substring-after($data,';')"/>
<xsl:with-param name="prevData" select="substring-before($data,';')"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
Hope this helps
If third is word isn't what you require everytime then you need the data that tells which word you need and accordingly change the number in find template to suit your need
