How to read xml elements in Bpel

Question

Hi,
I had created an empty Bpel Process and configured file adapter to a directory, In my text file i have 3 records with four columns, each column seperated by ',' and each record seperated by "EOL(end of line)", Below is the xsd file generated by the native format xsd builder, taken a recieve activity to recieve the contents of file from file adapter.
So all the data which is in the file will be there in recieve activity.
FileContents
55555,rgfdgsd,gfdgfdg,23
66666,retretret,trtertg,21
77777,rtrttreter,trtter,23
My Question is
I want to compare whether value of C1 = '55555' and if the value is equal to 55555 then that record with c1=55555 has to be inserted into database
How to compare the value of c1 through bpel functions.
with java i have to use the logic similar to this by using Xpath
getElement by tagname(c1);- it will give all the elements with tagname c1, three records are there with tagname c1 (c1=55555,c1=66666,c1=77777), we have to iterate through the elemnts and check whether the value iof c1='55555' and get the whole parent block which contains values of c1,c2,c3,c4 and insert that to database
What variables we have to use to get the Similar logic in bpel

Hello,
Create a transform between the out variable of you receive activity and in variable of your db adatpter.
The use an IF in you tranformation file.
Sample code
<xsl:template match="/">
<ns0:TestRahulCollection>
<xsl:for-each select="/tns:Root-Element/tns:element">
*<xsl:if test="xp20:matches(tns:C1,'55555')">*
<ns0:TestRahul>
<ns0:a1>
<xsl:value-of select="tns:C1"/>
</ns0:a1>
<ns0:a2>
<xsl:value-of select="tns:C2"/>
</ns0:a2>
<ns0:a3>
<xsl:value-of select="tns:C3"/>
</ns0:a3>
<ns0:a4>
<xsl:value-of select="tns:C4"/>
</ns0:a4>
</ns0:TestRahul>
</xsl:if>
</xsl:for-each>
</ns0:TestRahulCollection>
</xsl:template>
Thanks
