looking for xslt example using filtering

I'm looking for an example of how to filter out a value for display. I'm trying to use this logic to change something in the short item display. So, for example,

Given:
<a>123_abc</a>
<a>456_abc</a>
<a>789_abc</a>

if <a> does NOT contain 123, display this:

Label: 456_abc
789_abc

in the case where <a> only contains 123, don't display anything.

So if you have
<a>123_abc</a>

You should not display anything - just skip it.

Thank you!
Jose

Re: looking for xslt example using filtering

Here's a template that will do it. It could be simpler, but I tried to
make it illustrate the concept. Let me know if there is something you
don't understand.

<xsl:template match="a">
    <xsl:choose>
        <xsl:when test=". != '123_abc'">
            <xsl:copy-of select="." />
        </xsl:when>
        <xsl:otherwise>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

Re: looking for xslt example using filtering

I think in both of these cases the Label will be printed in each line. I want Label only to appear in the 1st line.

I'm thinking of using a variable to contain all the nodes I need, so I have this so far ( note that now the example has to do with what I'm actually working on )

<xsl:variable name='alluris' select="dim:field[ <at> element='identifier' and <at> qualifier='uri']"></xsl:variable>

But what I really want is for the variable alluris to contain all the uris except the handle, so I want to add something like this:

not(contains(./node(),'OUR_HANDLE_PRFIX'))

to the variable, but how do I add that to the to the select in the variable declaration (syntax)?

I think once I have a list of things I want to display, I can go from there.

Thank you!
Jose

I don't understand. What do you mean by lines?

Here are two ways to achieve the same thing. If the node doesn't
contain OUR_HANDLE_PREFIX, the variable will be assigned an empty
string.

<xsl:variable name='alluris'>
    <xsl:if test="not(contains(./node(),'OUR_HANDLE_PREFIX'))">
        <xsl:value-of select="dim:field[ <at> element='identifier' and
 <at> qualifier='uri']">
    </xsl:if>
</xsl:variable>

<xsl:choose>
    <xsl:when test="not(contains(./node(),'OUR_HANDLE_PREFIX'))">
        <xsl:variable name='alluris'
select="dim:field[ <at> element='identifier' and
 <at> qualifier='uri']"></xsl:variable>
    </xsl:when>
    <xsl:otherwise>
    </xsl:otherwise>
</xsl:choose>

Also note that "." is equivalent to "./node()".

Re: looking for xslt example using filtering

I think I got it. Here is what I have (TEMP-BOGUS is our handle prefix in dev. ):

<xsl:variable name='alluris' select="dim:field[ <at> element='identifier' and <at> qualifier='uri'][not(contains(.,'TEMP-BOGUS'))]"></xsl:variable>

Thanks!

Yes, that's another possible notation. And the most concise.
