Hi,

Here is my xsl file:

Code:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="no" method="text"/>

    <xsl:template match="/">

        Part Number#9;Part Description#9;Part Quantity#9;Part Find Number#9;Part Comments<xsl:text>#10;</xsl:text>
        <xsl:apply-templates select="*/*/*/Line"/>

    </xsl:template>

    <xsl:template match="Line">
        <xsl:apply-templates select="EBOMComponentName"/>
        <xsl:apply-templates select="EBOMDescription"/>
        <xsl:apply-templates select="EBOMQty"/>
        <xsl:apply-templates select="EBOMFindNumber"/>
        <xsl:apply-templates select="SeeNote"/>
        <xsl:text>
        </xsl:text>
    </xsl:template>

    <xsl:template match="EBOMComponentName">

        <xsl:if test="node()[not(.='null')]">
            <xsl:apply-templates/>
        </xsl:if>
        <xsl:text>    </xsl:text>
    </xsl:template>

    <xsl:template match="EBOMDescription">

        <xsl:if test="node()[not(.='null')]">
            <xsl:apply-templates/>
        </xsl:if>
        <xsl:text>    </xsl:text>
    </xsl:template>

    <xsl:template match="EBOMQty">

        <xsl:if test="node()[not(.='null')]">
            <xsl:apply-templates/>
        </xsl:if>
        <xsl:text>    </xsl:text>
    </xsl:template>

    <xsl:template match="EBOMFindNumber">

        <xsl:if test="node()[not(.='null')]">
            <xsl:apply-templates/>
        </xsl:if>
        <xsl:text>    </xsl:text>
    </xsl:template>

    <xsl:template match="SeeNote">

        <xsl:if test="node()[not(.='null')]">
            <xsl:apply-templates/>
        </xsl:if>
    </xsl:template>

</xsl:stylesheet>

What I can't figure out is how to only pull the records from the xml that have a value in the EBOMComponentName node. I know its something simple and I'm just missing it. It anyone can help that would be great. Thanks in advance.

.='null' compares the value of the current context with the string 'null', so unless our node actually contains the string 'null' then this will always equal false.

Have you tried "node()[.]" or "node()[empty(.)]"?

Actually the predicate [.] will always be true when applied to a node (the node exists), and the predicate [empty(.)] will always be false (the sequence containing the node is not empty). You haven't shown the source document and it's nto entirely clear what you requirement is, but I suspect it is test="string(.)"
