Subject: How can I get a value from the first child node ?
Author: Alex Star

In the file below root element <MorganData> has multiple child records where each one is a combination of single <HeaderRecord> and multiple <DataRecord>.
Hovewer, both childs are on the same level.

My question is next: For each <HeaderRecord>, How can I get a value <ClosingBal> from the first child <DataRecord> node only? I do not care about all other nodes, but I need a very first child one.

Here is a structure of the file

<MorganData xmlns="http://3wworld.schemas">
<HeaderRecord xmlns="">
<HeaderRecord_Child1>42929</HeaderRecord_Child1>
</HeaderRecord>
<DataRecord xmlns="">
<SettledCash>129418.81</SettledCash>
<DataRecord_Child20>120907.22</DataRecord_Child20>
<ClosingBal>2495529</ClosingBal>
</DataRecord>
<DataRecord xmlns="">
<SettledCash>140418.81</SettledCash>
<DataRecord_Child20>120907.22</DataRecord_Child20>
<ClosingBal>2405529</ClosingBal>
</DataRecord>
<HeaderRecord xmlns="">
<HeaderRecord_Child1>42929</HeaderRecord_Child1>
</HeaderRecord>
<DataRecord xmlns="">
<SettledCash>129418.81</SettledCash>
<DataRecord_Child20>120907.22</DataRecord_Child20>
<ClosingBal>2495529</ClosingBal>
</DataRecord>
<HeaderRecord xmlns="">
<HeaderRecord_Child1>42929</HeaderRecord_Child1>
</HeaderRecord>
<DataRecord xmlns="">
<SettledCash>141418.81</SettledCash>
<DataRecord_Child20>120907.22</DataRecord_Child20>
<ClosingBal>2895529</ClosingBal>
</DataRecord>
<DataRecord xmlns="">
<SettledCash>154418.81</SettledCash>
<DataRecord_Child20>120907.22</DataRecord_Child20>
<ClosingBal>2565529</ClosingBal>
</DataRecord>
<DataRecord xmlns="">
<SettledCash>187418.81</SettledCash>
<DataRecord_Child20>120907.22</DataRecord_Child20>
<ClosingBal>2125529</ClosingBal>
</DataRecord>
</MorganData>

This would be a heck of a lot easier if your data was in the following format:

<MorganData xmlns="http://3wworld.schemas">
<HeaderRecord xmlns="">
<HeaderRecord_Child1>42929</HeaderRecord_Child1>
<DataRecord xmlns="">
<SettledCash>129418.81</SettledCash>
<DataRecord_Child20>120907.22</DataRecord_Child20>
<ClosingBal>2495529</ClosingBal>
</DataRecord>
</HeaderRecord>
</MorganData>

Where each DataRecord was a child of each associated HeaderRecord.

Since this is not the case, you could keep track of the position of each element in your xpath results. Something like this:

/ns1:MorganData/HeaderRecord[position()=1]/HeaderRecord_Child1

For this header, get the ClosingBal:

/ns1:MorganData/DataRecord[position()=1]/ClosingBal

I am trying to build XSLT template and it is not going well so far.
I do not understand how can I call first <DataRecord> node from the inside a <HeaderRecord> loop.
Here is what I got:

<xsl:for-each select="//HeaderRecord">
<xsl:call-template name="firstnode"/>
<xsl:for-each select="./DataRecord">
<xsl:call-template name="regular"/>
</xsl:for-each>
</xsl:for-each>

Inside first "for-each" I got next data:
<HeaderRecord>
<HeaderRecord>
<HeaderRecord>
<HeaderRecord>
<HeaderRecord>
<HeaderRecord>

I want to call template "firstnode" after the each iterations of the "HeaderRecord".
Next step is to get a value from the very first following <DataRecord> node, so my question is how can I access a its value?
The XPath /ns1:MorganData/HeaderRecord[position()=1]/HeaderRecord_Child1 does not work(it is pointed to the wrong node).

As you said, if file would have a different structude, it would be less difficult.
Hovewer, all "HederRecord" and "DataRecord" are on the same level.

My apologies. I thought your data was one header record followed by one data record. The position xpath would have worked in this case, if the position was passed as a parameter to another template.

You can still do something similar though. Like this:

/ns1:MorganData/HeaderRecord[position()=1]/HeaderRecord_Child1/following::DataRecord[position()=1]/ClosingBal

This would retrieve the first ClosingBal following the first HeaderRecord.

/ns1:MorganData/HeaderRecord[position()=2]/HeaderRecord_Child1/following::DataRecord[position()=1]/ClosingBal

This would retrieve the first ClosingBal following the second HeaderRecord, and etc.

So, you can construct a for-each, a template that requires a parameter, pass the position as that parameter, and use a similar xpath as the second example above to retrieve the ClosingBal you are interested in.

Good luck.

Thank you for the help. I finally made it work. I found a different solution. I could actually ignore completelly all "HederRecord" nodes since all information is repeted in the trailing "DataRecord" elements. So, I used next expression to look for new node only and disregards any other following nodes:

<xsl:if test="not(PortfolioID=preceding-sibling::DataRecord/PortfolioID)">
<xsl:call-template name="getfirstnode"/>
</xsl:if>

I am sorry, I did not explained before in more details. Also, the data-sample I gave in the original post does not represent properly a source document I have. Sorry about it.

Best regards,

Alex Star
