Subject: Dynamic Input Rows and Validation in XSLT
Author: shahul hameed

Group,

I am new to XSLT. Based on the DB Query i am constructing dynamic rows of Input text boxes like

<xsl:element name="input">
<xsl:attribute name="name"><xsl:value-of select="concat('paymentamount',position())"/></xsl:attribute>
<xsl:attribute name="type">text</xsl:attribute>
</xsl:element>

so I am getting <input type="text" name="paymentamount1">,<input type="text" name="paymentamount2">, depends on the db result.

Now when the form is submitted i need to check whether the input boxes are not null. In any of the rows if the paymentamount is null i need to display the whole form with the data filled in for the rows that have been filled already.

I tried like this way...

<xsl:choose>
<xsl:when test="concat('/pp:document/pp:param[@name="paymentamount"]',position())[@value !='']"> -->
<xsl:attribute name="value">Electronic</xsl:attribute>
</xsl:when>
</xsl:choose>

I tried SingleQuote instead of &quote; i get an error. Could somebody shed some light on my problem..

I tried the below way

<xsl:for-each ....>
<xsl:variable name="myvalue"><xsl:value-of select="[@value !='']"/></xsl:variable>
<xsl:variable name="paymentdate"><xsl:value-of select="concat('paymentdate',position())"/></xsl:variable>
<xsl:variable name="paymentamount"><xsl:value-of select="concat('paymentamount',position())"/></xsl:variable>
<xsl:variable name="paymentamountcheck"><xsl:value-of select="concat($paymentamount,$myvalue)"/></xsl:variable>

<xsl:choose>
<xsl:when test="$paymentamountcheck">

....
....

</xsl:when>
</xsl:choose>
</xsl:for-each>

When executed i am getting the below error:

com.pp.presentation.content.CacheLoadException: Can not load a new Transformer for core/payment/onetimeSetup.xsl: javax.xml.transform.TransformerConfigurationException: javax.xml.transform.TransformerConfigurationException: javax.xml.transform.TransformerException: javax.xml.transform.TransformerException: A location path was expected, but the following token was encountered: [

Any help please to handle multiple rows and its validation and screen display for my situation.

Thanks in advance

Try moving the string out of the test= attribute. By putting it into
a variable, you avoid having to try to escape quotes.

<xsl:variable name="test1"><xsl:value-of select="paymentamount"/></xsl:variable>
<xsl:choose>
<xsl:when test="concat('/pp:document/pp:param[@name=$test1]',position())[@value !='']"> -->
<xsl:attribute name="value">Electronic</xsl:attribute>
</xsl:when>
</xsl:choose>
