Thymeleaf Build-Up a String

I want to create a string variable in thymeleaf by iterating through a loop and concatenating values into this string variable. Then i want to display this string in a <span> element. What i want to achieve can be written in java as follows:

String forDisplay = "";
foreach (MyObject o : myObjectCollection) {
   if (o.type == 1) { forDisplay += o.stringValue; }
}

Then in i want to put this in an html element like span. I know how to use:

<span th:each="o : ${objectCollection}" th:if="${o.type == 1}" th:text="${o.stringValue}"></span>

But this creates <span> for each of the elements that satisfy the condition. I just want to build-up my string in a th tag free section and then i just want to display my string in a single <span> element.

Here is how I join numbers into string using ", " as delimiter

<span th:each="instrumentDescriptor, iterStat : ${instrument.instrumentDescriptors}" th:text="!${iterStat.last} ? ${instrumentDescriptor.instrumentVersion} + ', ': ${instrumentDescriptor.instrumentVersion}"></span>

Ahmet, take a look at Expression Utility Objects for Strings, from Thymeleaf docs.

You have three methods for joining items:

${#strings.arrayJoin(namesArray,',')} // For Arrays
${#strings.listJoin(namesList,',')} // For Lists
${#strings.setJoin(namesSet,',')} // For Sets

These Utility Objects offers lots of cool methods for Aggregation, Calendars and etc.
