XSLT Tag - Hidden Input Form Fields

Hi,

If I have an XML file with multiple criteria (namely, Lastname, Insurance, Language):

<Params>
<Criteria>
<Criterion>
<Type>Lastname</Type>
<Name>S</Name>
</Criterion>
<Criterion>
<Type>Insurance</Type>
<Name>Empire Health</Name>
</Criterion>
<Criterion>
<Type>Language</Type>
<Name>French</Name>
</Criterion>
</Criteria>
</Params>

How would I be able to submit all these values as hidden input form fields in my XSLT?

I am already sending in SessionID:

<input type="hidden" name="SessionID" value="{@SessionID}">

and a single Search Criterion:

<input type="hidden" name="{Params/Criteria/Criterion/Type}" value="{Params/Criteria/Criterion/Type}">

I fear I am missing the situation where multiple search criteria are within the XML and will not be returned. .. How would I iterate between all the values within the Criterion, so as to not miss sending those Criterion values in?

Any advice or guidance is greatly appreciated!

Best regards,
Jamie

Slight correction, the single search criterion i am sending is:

<input type="hidden" name="{Params/Criteria/Criterion/Type}" value="{Params/Criteria/Criterion/Name}">

This is what I have so far:

<xsl:if test="count(Params/Criteria/Criterion) >0">
<xsl:for-each select="Params/Criteria/Criterion">
<xsl:if test="Name/text()">

<input type="hidden" value="{Params/Criteria/Criterion/Name}" name="{Params/Criteria/Criterion/Type}"></input>

and for testing purposes (to print out what's in the XML) <xsl:value-of select="Name"></xsl:Value-of>

</xsl:if>
</xsl:for-each>
</xsl:if>

What am I doing wrong?

Something like this should do the trick:


<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="html" encoding="iso-8859-1" />

    <xsl:template match="Params">
        <xsl:apply-templates />
    </xsl:template>

    <xsl:template match="Criterion">
        <xsl:element name="input">
            <xsl:attribute name="type">hidden</xsl:attribute>
            <xsl:attribute name="name"><xsl:value-of select="Type" /></xsl:attribute>
            <xsl:attribute name="value"><xsl:value-of select="Name" /></xsl:attribute>
        </xsl:element>
    </xsl:template>

</xsl:stylesheet>



Hope this helps.

Or just fix the XPath:

<input type="hidden" value="{Name}" name="{Type}"></input>

When you do something like:

<xsl:for-each select="Params/Criteria/Criterion">

you're changing the context inside the for-each, so now your XPath expressions should be relative to the current Criterion node.
