Cross-posted from EndUserSharePoint.com… Another day, another wunnerful article about the DVWP. This time, I’m going to cover some of the most useful “built-in” Field / Node functions. These are functions that are a part of XSL itself and help you work with nodes in the result set. A node is a geekier term for a…
Cross-posted from EndUserSharePoint.com… If you’ve been following this series, you’ve seen me write about the ddwrt namespace functions multiple times. They are extremely helpful functions that really aren’t documented in any formal way. A few of them show up in the XPath Expression Builder, but most of them are a mystery unless you find Serge…
Cross-posted from EndUserSharePoint.com… In the last article, I talked about teasing out the various parts of the values in Person or Group column values. To do this, I relied on the substring functions which are available to us in XSL. In this article, I’ll go over a few of those string functions and show you…
Cross-posted from EndUserSharePoint.com… As I got into writing this “last” article in the series, I realized that between the things people have asked me over the course of the series and the things I think might be useful, I have far more than one more article to write. I think I’ll keep this series going…
Cross-posted from EndUserSharePoint.com… <xsl:value-of> Outputs the value to which it evaluates, whether it be the value of a column, a variable, etc. <xsl:value-of> is sort of the “biggie” XSL tag. It’s what you use to output values of things that are variable. Pretty much every other tag we’ve talked about exists to get you to…
Cross-posted from EndUserSharePoint.com… <xsl:choose> Like <xsl:if>, but with multiple possibilities, more like if-then-else. <xsl:when> Used within <xsl:choose> as a conditional test. If the test is true, then the contained code is executed and the <xsl:choose> is exited. <xsl:otherwise> Used within <xsl:choose> as the “fall-back” condition. If none of the prior <xsl:when>s have been executed, the…
Cross-posted from EndUserSharePoint.com… <xsl:if> A single conditional test. If the test is true, then the contained code is executed. <xsl:if> is one of the simple workhorses in the Data View Web Part (DVWP) XSL arsenal. Its entire goal in life is to determine whether the code it contains is executed or not. Looking at our…
Cross-posted from EndUserSharePoint.com… <xsl:sort> Used within an <xsl:for-each> to determine the sort order in which the nodeset (group of rows) are processed. <xsl:sort> allows you to change the default sort order of the items as they are displayed in a Data View Web Part (DVWP). By default (in almost all cases), the items will be…
Cross-posted from EndUserSharePoint.com… <xsl:for-each> A way to iterate over a nodeset (group of rows). Once you have a rowset like the $Rows I talked about in the prior article about <xsl:variable>, you’ll want to do something with it. If you’ve ever used a report writer or created reports in an application like Microsoft Access, the…
Cross-posted from EndUserSharePoint.com… <xsl:variable> A value you create for use within a template which is only defined within the scope of that template. Parameters and variables are used interchangeably, but how you create them is a bit different. While a parameter is a value which you expect to receive, a variable is something which you…
