Filter Idoc segment based on date in XSLT map

Question

Hi,
In a Idoc to flat file XSLT mapping, I have a requirment to filter segment out of multiple segment occurance in HRMD_A idoc. Idoc has two date fields(actually string data, containing date in YYYYMMDD format) in the segment(end date and start date). I need to filter only one segment from multiple segments where current date falles within start and end dates (end date >= current date >= start date). Then map output fields from the filtered segment.
Its easy doing it in graphical mapping, but its difficult to use graphical mapping here as the message structure are enormous. I dont have much hands on in XSLT but think many of you have been through this kind of requirement using XSLT. So holding my hope high :). Please suggest a logic for this, will be highly appretiated.

Suman.

Answer 1

This functions will give you the current date:
fn:current-dateTime()     => Returns the current dateTime (with timezone)
fn:current-date()                 => Returns the current date (with timezone)
fn:current-time()                 => Returns the current time (with timezone)
To compare:
fn:compare(comp1,comp2)
fn:compare(comp1,comp2,collation)
=> Returns -1 if comp1 is less than comp2, 0 if comp1 is equal to comp2, or 1 if comp1 is greater than comp2 (according to the rules of the collation that is used)
Example: compare('ghi', 'ghi')
Result: 0
Also I suggest working with an IF condition like this:
<xsl:if test="price &gt; 10">
        <tr>
          <td><xsl:value-of select="title"/></td>
          <td><xsl:value-of select="artist"/></td>
        </tr>
      </xsl:if>
