However, the statement: "xsl:apply-templates is a loop" isn't correct. Implementation differences on the XSLT processor's end will not affect me as an XSLT programmer, the outcome is absolutely the same for parallelized and iterative implementations alike.

Tomalak: While this may be useful for novice XSLT programmers, I think it is often misleading to them as they think that they can re-use state information accumulated in the "execution of the loop".

Tomalak: Because of these facts, I think that it would be appropriate to modify "xsl:apply-templates is a loop"with somethinkg like: "xsl:apply-templates is like a loop" — Dimitre Novatchev.

To add to the good answer by Tomalak: Here are some unmentioned and important differences : xsl:apply-templates is much richer and deeper than xsl:call-templates and even from xsl:for-each , simply because we don't know what code will be applied on the nodes of the selection -- in the general case this code will be different for different nodes of the node-list.

If we add a select attribute to the xsl:apply-templates element it will process only the child element that matches the value of the attribute.

For each, it locates the template with the highest priority that matches the node, and invokes it. Unnamed templates, also known as match templates, include a match attribute that contains an XPath expression to specify the criteria for nodes upon which the template should be invoked. In the following example, the template applies to the element named route that is a child of the current context and that has a child element named next-hop whose value starts with the string By default, when XSLT processes a document, it recursively traverses the entire document hierarchy, inspecting each node, looking for a template that matches the current node.

When a matching template is found, the contents of that template are evaluated. Otherwise all children of the context node are traversed. If the select attribute is included, but does not match any nodes, nothing is traversed and nothing happens. All the nodes containing a changed attribute are processed. Using unnamed templates allows the script to ignore the location of a tag in the XML hierarchy. Named templates operate like functions in traditional programming languages, although with a verbose syntax.

I suspect that it's easier if they are separate templates but I may be wrong. Add a comment. Active Oldest Votes. Martin Honnen Martin Honnen k 6 6 gold badges 80 80 silver badges 97 97 bronze badges. Thank you!

The other site utilities-online. Is there any online tool were I can check it? I have put an XSLT 2 version where the xsl:mode have been spelled out by the identity transformation at xsltransform.

Can you, please, explain a bit more how it works? I've tried applying it to my original problem and what I got is concatenation of all the strings that are in my tags, witout tags I have tried both variations. I assume that template with mode equal to step1 is not executed immediately but rather as assignment to the variable.

Then there is apply-templates which I'm not sure how it works, but I guess it calls the last template. I'm about to read more about modes. If you want to learn XSLT then cranesoftwrights. Sign up or log in Sign up using Google.
