    <p>I have a RSS XML news file, which contains a list of items inclusive of a URL to an image. I also have an associated XSLT.</p> <p>The problem is that the image sizes are not consistent and I want to limit the image sizes, resize them, to a nice thumbnail.</p> <p>How would I modify the XSLT to accomplish that?</p> <p>XML Sample:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt; &lt;rss version ="2.0" xmlns:g="http://base.google.com/ns/1.0"&gt; &lt;channel&gt; &lt;title&gt;Company Name&lt;/title&gt; &lt;description&gt;Company description&lt;/description&gt; &lt;link&gt;http://www.mycompanyurl.com&lt;/link&gt; &lt;item&gt; &lt;title&gt;News Item Title&lt;/title&gt; &lt;link&gt;http://www.whateverurl.com/&lt;/link&gt; &lt;category&gt;Space&lt;/category&gt; &lt;pubDate&gt;12 April 1961&lt;/pubDate&gt; &lt;description&gt;Software to reduce your job search to a half hour per day. all major job sites, job boards, classifieds. unemployment paperwork, CRM, interviews, more&lt;/description&gt; &lt;image&gt; &lt;url&gt;~/App_Data/NewsControl/whatever.png&lt;/url&gt; &lt;title&gt;Whatever1&lt;/title&gt; &lt;link&gt;javascript:void(0)&lt;/link&gt; &lt;/image&gt; &lt;g:id&gt;1&lt;/g:id&gt; &lt;g:brand&gt;Whatever2&lt;/g:brand&gt; &lt;g:condition&gt;whatever3&lt;/g:condition&gt; &lt;g:price&gt;$whatever4&lt;/g:price&gt; &lt;g:product_type&gt;Whatever5&lt;/g:product_type&gt; &lt;/item&gt; &lt;/channel&gt; &lt;/rss&gt; </code></pre> <p>Here is the associated XSLT:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:template match="/"&gt; &lt;items&gt; &lt;xsl:for-each select="//item"&gt; &lt;item Name="{position()}" HeaderText="{title}" Text="{description}" NavigateUrl="{position()}" Date="{pubDate}" ImageUrl="{image/url}"/&gt; &lt;/xsl:for-each&gt; &lt;/items&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p><strong>Results of First Answer</strong>:</p> <pre><code>&lt;items&gt; &lt;xsl:for-each select="//item"&gt; &lt;item Name="{position()}" HeaderText="{title}" Text="{description}" NavigateUrl="{position()}" Date="{pubDate}" ImageUrl="/Tools/thumber.php?img={image/url}"/&gt; &lt;/xsl:for-each&gt; &lt;/items&gt; </code></pre> <p>I made these changes, enabled PHP on the server (testing on from the server and locally), and saw 2 issues: 1. I get no image, merely a no image box.</p> <ol> <li>If I try to edit the ImageUrl and tack on a "&amp;W=xxx&amp;H=xxx", the Visual Studio validator complains and throws up errors on the &amp;.</li> </ol> <p><strong>Update 2</strong> Here is the latest line in the XSLT: http://myserver.com/Tools/thumber.php?img=',image/url)}"/></p> <p>The corresponding image section in the XML</p> <pre><code>&lt;image&gt; &lt;url&gt;/Products/Jobfish/Images/Boxshots/Jobfish_DVDCaseCD_ShadowOut.jpg&lt;/url&gt; &lt;title&gt;Jobfish&lt;/title&gt; &lt;link&gt;javascript:void(0)&lt;/link&gt; </code></pre> <p></p>

    1. COThis `/Tools/thumber.php?img={image/url}` is wrong, you cannot evaluate as an expression only part of an attribute - it should be `{concat('/Tools/thumber.php?img=',image/url)}`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
