Re: How is this web service working?

Here's a snippet of the source. The program seems to simply get the xml
data, call a program and set the xml data. But where is the data?

<file version="1.0" encoding="UTF-8" wss="yes" soap="yes">

<headers>

<header keyword="datedit(*ymd)"/>

</headers>

<definitions>

<parameters>

<param name="FILEXMLIN" type="A" length="640"/>

<param name="FILEXMLOUT" type="A" length="640"/>

</parameters>

<files>

<diskfile key="yes" name="FILEP1" usage="U"/>

<diskfile key="yes" name="FILEP2" usage="U"/>

</files>

<fields>

<field name="MYFIELD1" type="A" length="3"/>

<field name="MYFIELD2" type="S" length="9" decimal="0"/>

</fields>

<klists>

<klist name="key1">

<kfld name="keyfield1"/>

</klist>

</klists>

<prototype/>

</definitions>
