Question

We are using XSL to convert a XML file into a pipe-delimited format.

<?xml version="1.0" encoding="UTF-8"?>
<ns:tradedata xmlns:ns="http://schemas.com/enterprise/util/extractservice/v1">
    <tradedata_item>
        <ORDER_ID>113632428</ORDER_ID>
        <CUSIP>31393FHA7</CUSIP>
        <TICKER>FHR</TICKER>
        <SEC_NAME>FHR 2527 SG</SEC_NAME>
        <ORDER_QTY>169249.6824</ORDER_QTY>
    </tradedata_item>
    <tradedata_item>
        <ORDER_ID>113632434</ORDER_ID>
        <CUSIP>31393G2C7</CUSIP>
        <TICKER>FHR</TICKER>
        <SEC_NAME>FHR 2531 ST</SEC_NAME>
        <ORDER_QTY>214673.0105</ORDER_QTY>
    </tradedata_item>
    <tradedata_item>
        <ORDER_ID>113632431</ORDER_ID>
        <CUSIP>527069AH1</CUSIP>
        <TICKER>LESL</TICKER>
        <SEC_NAME>ZZZ_LESLIE S POOLMART INC</SEC_NAME>
        <ORDER_QTY>365000.0000</ORDER_QTY>
    </tradedata_item>
</ns:tradedata>

We need the first line in the output to be the column headers, and everything else would be data, like this…

ORDER_ID|CUSIP|TICKER|SEC_NAME|ORDER_QTY
1136324289|31393FHA7|FHR|FHR 2527 SG|169249.6824
1136324304|31393G2C7|FHR|FHR 2531 ST|214673.0105

We’ve got the XSL working to get the data, but we can’t get the header to output correctly. We just select the first tradedata_item element, then iterate the element name and separate them using | characters. Here is the full XSL…

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" exclude-result-prefixes="xsl"
    version="1.0" xmlns="http://schemas.com/enterprise/util/extractservice/v1"
    xmlns:o="http://schemas.com/enterprise/util/extractservice/v1" > 

    <!--  xsl:strip-space elements="*"/-->
    <xsl:output method="text" indent="no"/>

     <xsl:template match="/tradedata/tradedata_item[1]">
    <xsl:for-each select="*">
      <xsl:value-of select="local-name()"/>|
    </xsl:for-each>
    <xsl:text>&#10;</xsl:text>  
  </xsl:template>


    <xsl:template match="/">
    <xsl:for-each select="tradedata/tradedata_item">
    <xsl:value-of select="ORDER_ID"/>|<xsl:value-of select="CUSIP"/>|<xsl:value-of select="TICKER"/>|<xsl:value-of select="SEC_NAME"/>|<xsl:value-of select="ORDER_QTY"/>
    <xsl:text>&#10;</xsl:text>
    </xsl:for-each>
    </xsl:template>
    </xsl:stylesheet>

The output we’re seeing is just data, no header…

113632428|31393FHA7|FHR|FHR 2527 SG|169249.6824
113632430|31393G2C7|FHR|FHR 2531 ST|214673.0105
113632431|527069AH1|LESL|ZZZ_LESLIE S POOLMART INC|365000.0000
113632434|38470RAD3|GRAHAM|ZZZ_GRAHAM PACKAGING CO|595000.0000

Please disregard any namespace inconsistencies; I had to obfuscate the xml and xsl for legal reasons.

Try this :

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" indent="no"/>

<xsl:template match="/">
<xsl:for-each select="tradedata/tradedata_item[1]/*">
  <xsl:value-of select="concat(name(), '|')"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Output :

ORDER_ID|CUSIP|TICKER|SEC_NAME|ORDER_QTY|

It seems pretty simple to me. Maybe your error lies elsewhere.
