In BizTalk the following Flat Files schema would parse it, Field2 containing what you are after.
<?xml version="1.0" encoding="utf-16"?>
<xs:schema xmlns="http://Scratch2.SO72451573" xmlns:b="http://schemas.microsoft.com/BizTalk/2003" targetNamespace="http://Scratch2.SO72451573" xmlns:xs="http://www.w3.org/2001/XMLSchema">

<schemaEditorExtension:schemaInfo namespaceAlias="b" extensionClass="Microsoft.BizTalk.FlatFileExtension.FlatFileExtension" standardName="Flat File" xmlns:schemaEditorExtension="http://schemas.microsoft.com/BizTalk/2003/SchemaEditorExtensions" />

<xs:complexType>

</xs:annotation>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Would parse it into the following XML
<Root xmlns="http://Scratch2.SO72451573">
