SC longtext transfer

Hi experts

I use PI and PurchaseRequestRequest_In for shopping card creating in SRM 7.02 system.

There is problem with longtext transfer : only last string of text from XML data are creating in shopping card.

This is part of XML file responcible for long text :

<TextCollection>

<Text ActionCode="01">

  <TypeCode>A05</TypeCode>

  <ContentText>String 1</ContentText>

</Text>

<Text ActionCode="01">

  <TypeCode>A05</TypeCode>

  <ContentText>String 2</ContentText>

</Text>

<TextCollection>

Could you please get advice - how can I modify XML data for both strings be created in SC ?
