How to check if string is empty or not using <xsl:when test="

Thanks. I will test and get back .. also can you tell me how do we select the value if the above is the condition


Can you check if i am right


<xsl:choose>
                            <xsl:when test="p:PRACTICE_CODE = ''">
                            <xsl:value-of select="concat(string(p:PATIENTIRN),string('-'),string('unknown'),string('-'),string(p:FIRSTNAME),string(p:LASTNAME))"/>
</xsl:when>
 <xsl:when test="p:FIRSTNAME = ''">
                            <xsl:value-of select="concat(string(p:PATIENTIRN),string('-'),string('PC'),string('-'),string('unknown'),string(p:LASTNAME))"/>
</xsl:when>
                        <xsl:otherwise>
                                <xsl:value-of select="concat(string(p:PATIENTIRN),string('-'),string(p:PRACTICE_CODE),string('-'),string(p:FIRSTNAME),string(p:LASTNAME))"/>
                         </xsl:otherwise>
                        </xsl:choose>

I would do this slightly different

I would have a named template in my stylesheet
    <xsl:template name="makeDefault">
        <xsl:param name="str"/>
        <xsl:choose>
            <xsl:when test="string-length(normalize-space($str) = 0">
                <xsl:text>unknown</xsl:text>
            </xsl:when>
            <xsl:otherwise>
                <xsl:value-of select="$str"/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>

and then I would leave all the tests out of the main part
        <xsl:value-of select="p:PATIENTIRN"/>
        <xsl:text>-</xsl:text>
        <xsl:call-template name="makeDefault">
            <xsl:with-param name="str" select="p:PRACTICE_CODE"/>
        </xsl:call-template>
        <xsl:text>-</xsl:text>
        <xsl:call-template name="makeDefault">
            <xsl:with-param name="str" select="p:FIRSTNAME"/>
        </xsl:call-template>
        <xsl:text>-</xsl:text>
        <xsl:value-of select="p:LASTNAME"/>

no need for the string() function, it is all text coming from the source document

cheers

Geert, the above is little confusing for me sice i am not much in to this.

The above empty checking working fine for me.

can you tell how to do this

for instance i have string called Denise , Martin

i want that to be changed as    Denise Martin (remove the comma).

Like Name as  abc , xyz but i do not want comma in there.

I can open other question or increase points her

for removing the comma, all you need to do is
<xsl:value-of select="translate(., ',', '')"/>
where '.' is the context node

What is the context node in the above. can you give simple example? and also how to check 2 condition in <XSL:WHEN

like if f1 and f2 are empty..

Thanks a lot for the help.

How would i increase the points. Let me know. If not i would open other thread and assign you there.

you can't increase since 500 is the maximum,
and that is more than sufficient for this question,
don't worrie about the points

Hi I see one more issue here. I am not able to use transalte to remove comma as above in concat method . can you look below advise me how to do that. Right now below has error

<xsl:value-of select="concat(string(p:PRACTICE_CODE),string('-'),string(translate(p:PRIMARYCAREMANAGER,',',''))"/>
