RSS Viewer Customization

In order to customize the rendering of RSS Agregator web part default XSLT for RSS Feed should be changed (see Xsl property).

Usage

So, find the line for rendering feed item link:

<a href="{ddwrt:EnsureAllowedProtocol(string(link))}">More...</a>

and replace it with this one:

<a target="_blank" href="{ddwrt:EnsureAllowedProtocol(string(link))}">More...</a>

This will allow to open feed items in separate window.

Regarding PubDate, it should be rendered by default (see template RSSMainTemplate.description). Below is excerpt from it, that is used for rendering formatted PubDate:

<xsl:choose>
        <xsl:when test="string-length(pubDate) &gt; 0">
          <xsl:variable name="pubDateLength" select="string-length(pubDate) - 3" />
          <xsl:value-of select="ddwrt:FormatDate(substring(pubDate,0,$pubDateLength),number($rss_LCID),3)"/>
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="ddwrt:FormatDate(string(dc:date),number($rss_LCID),3)"/>
        </xsl:otherwise>
      </xsl:choose>

But of course it could be customized as well. For example to print PubDate in raw format the following Xslt could be used:

<xsl:value-of select="pubDate"/>

See the full source code for customized RSS Feed XSLT for details.

In order to display publication date for date part only the following Xslt could be used:

<xsl:value-of select="ddwrt:FormatDate(pubDate,number($rss_LCID),3)"/>

The RSS Web part allows for XSLT based customizations. If you are not fun of working direclty with XSLT, you could always use this XSLT to get the full RSS render as XML. This can than be used in SharePoint Designer as XML Data Source for any Data View web part, which will help you into easier manipulation.
