Problems while coping integer values

Hi all,

I am trying to copy an integer value in an attribute with the following
copy:

  <copy>
      <from>$counterParam</from>
      <to>$n0_PAAM_data_in.body/xsd:parameterSet/@id</to>
  </copy>

Where
  <variable messageType="xsd:paamInput" name="n0_PAAM_data_in" />
  <variable name="counterParam" type="xs:integer" />
and paamInput schema declares the attribute with a:
<xsd:attribute name="id" type="xsd:integer" use="optional"/>


The problem is that final result is:
<?xml version="1.0" encoding="UTF-8"?>
<PAAM_in xmlns="http://www.a-ware.org/test/xsd"
xmlns:xsd="http://www.a-ware.org/test/xsd">
<templateFile>pluto</templateFile>
		<parameterSet id="1.0">    <----------
                <xsd:parameter>
                        <xsd:name>string1</xsd:name>
                        <xsd:value>string1</xsd:value>
                </xsd:parameter>
       </parameterSet>
</PAAM_in>


While before the copy it was:
<parameterSet id="1">

Obviously the final message is invalid because the field that should be
an integer, is represented with a dot.

Is this a bug or am I doing something wrong?


thanks for your help,
Luca

It works now!

Thanks a lot,

Hi Luca,

The decimal form you're seeing is the default representation of numbers in
XPath.   If you want to drop the decimal, use the function
string($counterParam).   Here's what the XPath spec section 4.2 says about
the string() function:

if the number is an integer, the number is represented in decimal form as a
Number <http://www.w3.org/TR/xpath#NT-Number> with no decimal point and no
leading zeros, preceded by a minus sign (-) if the number is negative
