with a quick glace i can say u have given wrong xPath
u want to show doc elements
so xPath will be
//response/result/doc

Sep 03, 2010 06:45 AM|Peter Smith|LINK
Ok, but how would I then extract the values for these: 1. features (multivalued node) 2. title
Thanks! :)
Sep 03, 2010 08:09 AM|mehta.rahulit|LINK
those are not node those are attribute
make a search to get attribute in xslt
Sep 03, 2010 08:15 AM|Peter Smith|LINK
Im aware those not nodes:) But do you have an example on how I can do it (for my specific scenario)? Thanks again!

Showing Solr XML results in gridview using xmldatasource
Sep 03, 2010 05:03 AM|Peter Smith|LINK
I have the XML below, generated by Apache Solr.
I want to assign the results (2 <doc>nodes in this case) to a gridview using an XML datasource.
<response>
-
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">0</int>
<lst name="params">
<str name="facet">true</str>
<str name="fl">
id,title,city,score,location_rating,introtext,location_rating_total,themes,features,official,services
</str>
<str name="indent">on</str>
<str name="start">0</str>
<str name="q">*:*</str>
<arr name="facet.field">
<str>province_raw</str>
<str>services_raw</str>
<str>themes_raw</str>
<str>features_raw</str>
</arr>
<str name="fq">themes:Building</str>
<str name="rows">2</str>
</lst>
</lst>
<result name="response" numFound="2" start="0" maxScore="1.0">
<doc>
<float name="score">1.0</float>
<arr name="features">
<str>Garden</str>
<str>Cafe</str>
</arr>
<str name="id">1</str>
<str name="introtext">Boston, its awesome</str>
<float name="location_rating">3</float>
<int name="location_rating_total">2</int>
<arr name="services">
<str>Fotoreport</str>
</arr>
<arr name="themes">
<str>Building</str>
</arr>
<str name="title">Boston Mass</str>
</doc>
-
<doc>
<float name="score">1.0</float>
<arr name="features">
<str>Garden</str>
<str>Cafe</str>
<str>Dancing</str>
</arr>
<str name="id">2</str>
<str name="introtext">New york,some text</str>
<float name="location_rating">0</float>
<int name="location_rating_total">0</int>
-
<arr name="services">

</arr>
<arr name="themes">
<str>Building</str>
<str>Oldschool</str>
</arr>
<str name="title">New York av</str>
</doc>
</result>
I now have this:
<asp:GridView ID="gvSearchResults" DataSourceID="XMLDS" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<i>Name <%#XPath("title")%></i>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:XmlDataSource ID="XMLDS" runat="server"></asp:XmlDataSource>
I've been looking into XSL stylesheets as well, but if someone could help me out getting started it would be much appreciated!
