XSLT Select nodes without text-node children whose names starts with specifix text

[Michael Reiche]

Question on XSL expression

Got this XML:

<Body>
<Page>
<Line no="9" detail="true">
<onefield>onefieldstext</onefield>
<twofield>twofieldstext</twofield>
</Line>
<Line no="10" detail="true">
<onefield>onefieldstext</onefield>
<fgman9>fgmanfieldstext</fgman9>
<twofield>twofieldstext</twofield>
</Line>
<Line no="11" detail="true">
<onefield>onefieldstext</onefield>
<twofield>twofieldstext</twofield>
</Line>
<Line no="12" detail="true">
<onefield>onefieldstext</onefield>
<twofield>twofieldstext</twofield>
</Line>
<Line no="13" detail="true">
<onefield>onefieldstext</onefield>
<fgman5>fgmanfieldstext</fgman5>
<twofield>twofieldstext</twofield>
</Line>
<Line no="14" detail="true">
<onefield>onefieldstext</onefield>
<twofield>twofieldstext</twofield>
</Line>
</Page>
</Body>

I would select the <Line/> nodes without text-node children whose names is starting with "fgman" - in this example it is all <Line/> _except_ <fgman9/> and <fgman5/> in <Line/> with @no of 10 and 13.

I know that this works:

<xsl:for-each select="Body/Page/Line[@detail]">

<xsl:if test="count(fgman9|fgman5) = 0">
L<xsl:value-of select="@no"/>:<xsl:value-of select="onefield"/> </xsl:if>

<xsl:if test="fgman9">
<xsl:value-of select="@no"/> Ouuch</xsl:if>

<xsl:if test="fgman5">
<xsl:value-of select="@no"/> Whoops</xsl:if>

</xsl:foreach>

But as the <fgmanXXX/> nodes could be named fgman0 to fgman1000 I would prefer not to list everyone as arguments to the count expression.

I know that this works:

<xsl:for-each select="Body/Page/Line[@detail]">

<xsl:if test="count(fgman9|fgman5) = 0">
L<xsl:value-of select="@no"/>:<xsl:value-of select="onefield"/> </xsl:if>

<xsl:if test="fgman9">
<xsl:value-of select="@no"/> Ouuch</xsl:if>

<xsl:if test="fgman5">
<xsl:value-of select="@no"/> Whoops</xsl:if>

</xsl:foreach>

within a xsl:choose instruction you could filter out all elements having unwanted children using starts-with, eg:

<xsl:choose>
<xsl:when test="*[starts-with(name,'fgman')]" />
<xsltherwise>
L<xsl:value-of select="@no"/>:<xsl:value-of select="onefield"/> </xsltherwise> </xsl:choose>

A text node does not have a name -- probably you mean "whose parent's name" ..

is starting with "fgman" - in this example it is all <Line/> _except_ <fgman9/> and <fgman5/> in <Line/> with @no of 10 and 13.

Use:

/*/*/Line[not(*[starts-with(name, 'fgman')])] [text]

Exactly!!!

Use:

/*/*/Line[not(*[starts-with(name, 'fgman')])] [text]

Well actually I found:

<xsl:if test="not(*[starts-with(name, 'fgman')])">

to suit my needs.
