You can not export a List View Web Part, and you cannot use the resulting xml as a list def/template
The resulting xml of a export would look something like this:
<?xml version="1.0" encoding="utf-8" ?>
<webParts>
<webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
<metaData>
<type name="Microsoft.SharePoint.WebPartPages.XsltListViewWebPart, Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
<importErrorMessage>Cannot import this Web Part.</importErrorMessage>
</metaData>
<data>
<properties>
<property name="ListUrl" type="string">Lists/Kunngjoringer</property>
<property name="MissingAssembly" type="string">Cannot import this Web Part.</property>
<property name="JSLink" type="string">~sitecollection/_catalogs/masterpage/AnnouncementJSLink.js</property>
<property name="XmlDefinition" type="string"><View Name="{D7DB034A-98D9-4D03-8B85-3512DB00D704}" MobileView="TRUE" Type="HTML" Hidden="TRUE" DisplayName="" Url="/avdelinger/Serviceavdelingen/ikt/SitePages/Hjemmeside.aspx" Level="1" BaseViewID="1" ContentTypeID="0x" ImageUrl="/_layouts/15/images/announce.png?rev=23" ><Query><OrderBy><FieldRef Name="Modified" Ascending="FALSE"/></OrderBy></Query><ViewFields><FieldRef Name="LinkTitle"/><FieldRef Name="Modified"/><FieldRef Name="Body"/><FieldRef Name="Created"/><FieldRef Name="Author"/></ViewFields><RowLimit Paged="TRUE">30</RowLimit><Aggregations Value="Off"/><JSLink>clienttemplates.js</JSLink><XslLink Default="TRUE">main.xsl</XslLink><Toolbar Type="Standard"/></View></property>
</properties>
</data>
</webPart>
You could use the Xmldefintion as a view though.
