Question

if suppose my database having three row records by fetching that data i am converting into xml data as shown below :

Here is my XML:

<NewDataSet>
 <Table>
<RECORD_TYPE_CODE>CTD</RECORD_TYPE_CODE>
<MSG_TYPE_CODE>O103N</MSG_TYPE_CODE>
<CTD_SEQ_NUM>000086</CTD_SEQ_NUM>   
<CTD_CTD_PKG_ID>2</CTD_CTD_PKG_ID>
</Table>
<Table>
<RECORD_TYPE_CODE>CTO</RECORD_TYPE_CODE>
<MSG_TYPE_CODE>O203N</MSG_TYPE_CODE>
<CTD_SEQ_NUM>000087</CTD_SEQ_NUM>   
<CTD_CTD_PKG_ID>2</CTD_CTD_PKG_ID>
</Table>
<Table>
<RECORD_TYPE_CODE>CTH</RECORD_TYPE_CODE>
<MSG_TYPE_CODE>O303N</MSG_TYPE_CODE>
<CTD_SEQ_NUM>000088</CTD_SEQ_NUM>   
<CTD_CTD_PKG_ID>2</CTD_CTD_PKG_ID>   
</Table>
</NewDataSet>

through c sharp code behind using for loop i m sending package id (CTD_CTD_PKG_ID)and Sequencenum(CTD_SEQ_NUM) through xslt argument parameters it was passing properly in a sequential order like 000086,000087,000088 but first time for in aloop i will pass 000086 seqnum it was fetching proper manner next when i m passing 000087 it was generating data in table of 000086 only why it was happening passing parameter value is goin good in a sequential order

here is my XSLT:

    <xsl:param name="PackageId"  />
<xsl:param name="SequenceNum"  />
<xsl:template match="/">
<xsl:apply-templates mode="SequenceB"  select="(NewDataSet/Table[CTD_CTD_PKG_ID =$PackageId]    |   NewDataSet/Table[CTD_SEQ_NUM =$SequenceNum])[1]"/>
</xsl:template>

Answer 1

I guess (if my guess is incorrect, you need to explain better the problem) that the value of your $PackageId parameter is always defined as 2.

The XPath expression you are using:

    (NewDataSet/Table[CTD_CTD_PKG_ID =$PackageId]
   |
     NewDataSet/Table[CTD_SEQ_NUM =$SequenceNum]
     )
     [1]

selects the first node from the union of the nodes selected by:

NewDataSet/Table[CTD_CTD_PKG_ID =$PackageId]

and:

NewDataSet/Table[CTD_SEQ_NUM =$SequenceNum]

Do note, that if the value of the $PackageId parameter is 2, then the first node of theis union is always /*/Table[1].

The solution is to replace the XPath expression you are using with:

NewDataSet/Table[CTD_CTD_PKG_ID =$PackageId][CTD_SEQ_NUM =$SequenceNum]
