How to Select the First/Last Sibling in XSLT

(0 votes, average 0 out of 5)

From my experiences with using XSL to transform XML documents, I frequently find the need to test the name of either the sibling directly following or directly preceding a given node. Unfortunately, there is not XPATH expression that provides this functionality. The following code should give you what you are looking for, however.

Check to see if the first preceding sibling is "car":

<xsl:if test="name(preceding-sibling::*[1]) = 'car'">



</xsl:if>

Likewise, to test to see if the first following sibling is "car" use the following:

<xsl:if test="name(following-sibling::*[1]) = 'car'">



</xsl:if>

Here are some notes to keep your console looking fresh, clean, and working perfect. Don't forget, you need to use either the RF box that comes with the atari, or you can buy an RCA to Coax adapter. An automatic RF switching box will *not* work, because the atari signal isn't strong enough.Out of all of the consoles I like to work...

» Merge Two Versions of A Table Together in a Database

When keeping multiple versions of a website, or perhaps migrating a website to a new environment, it is often necessary to merge any changes between the two databases. The databases have the same structure, but each has new, unique content which needs to be added to the other. The following tutorial uses syntax for MySQL, however it should be applicable to other major database schemas. The following example assumes that the master database where we want all of the changes to reside is called...
