                                                    <xsl:if test="//Record/CIMtrek_CI_CER_Type/text()='Increase'">
                                                        <xsl:attribute name="selected">true</xsl:attribute>
                                                    </xsl:if>
                                                    Increase

                                                <option value="Decrease">
                                                    <xsl:if
                                                        test="//Record/CIMtrek_CI_CER_Type/text()='Decrease'">
                                                        <xsl:attribute name="selected">true</xsl:attribute>
                                                    </xsl:if>
                                                    Decrease
                                                </option>
                                            </select>

This is how i created combo box from the values which is in xml generated from SQL query :

<xsl:for-each select="//CIMtrek_CarrierName/Record">
                                                    <option>
                                                        <xsl:if
                                                            test="//Record/CIMtrek_RegWhseCo_Carrier/text()=@CIMtrek_CarrierName">
                                                            <xsl:attribute name="selected">true</xsl:attribute>
                                                        </xsl:if>
                                                        <xsl:attribute name="value"><xsl:value-of
                                                            select="@CIMtrek_CarrierName" />!@#$%^*!<xsl:value-of
                                                            select="@Carrier_LateContacts" />!@#$%^*!<xsl:value-of
                                                            select="@Carrier_Contacts1" />!@#$%^*!<xsl:value-of
                                                            select="@Carrier_Contacts2" />!@#$%^*!<xsl:value-of
                                                            select="@Carrier_Contacts3" /></xsl:attribute>
                                                        <xsl:value-of select="@CIMtrek_CarrierName" />
                                                    </option>
                                                </xsl:for-each>

with BeniBela answer i am not able to put things in, like the above code,

Hope BeniBela can help me to figure it out.

How to do this,

Please help me,

Best Regards.

Answer 1

The tokenize() function does exactly this. Note that takes a regular expression, so | has to be escaped as [|] leading to:

for $o in /Keywords/Record/tokenize(@CIMtrek_Keywords, "[|]") return
  <option value="{$o}">{$o}</option>

That new xml can be converted to xquery like this:

for $r in //CIMtrek_CarrierName/Record return  $r/
  <option value="{@CIMtrek_CarrierName}!@#$%^*!{@Carrier_LateContacts}!@#$%^*!{@Carrier_Contacts1}!@#$%^*!{@Carrier_Contacts2}!@#$%^*!{@Carrier_Contacts3}">
  {  if (//Record/CIMtrek_RegWhseCo_Carrier/text()=@CIMtrek_CarrierName) then attribute selected { "true" } else (),
     data(@CIMtrek_CarrierName)  }
  </option>

The intitial $r/ changes the context, so we do not need to write $r/ before every attribute access, the xsl:value-of becomes {..} and xsl:attribute becomes an xml-like attribute declaration or 'attribute name {..}'
