How to get related classes and values in JSoup?

I have an HTML file, a part of which looks like this:

<a name="user_createtime"></a>
<p class="column">
<span class="coltitle">CreateTime</span>&nbsp;&nbsp;<span class="titleDesc"><span class='defPopupLink' onClick='popupDefinition(event, "datetime")'>datetime</span></span>&nbsp;&nbsp;&nbsp;&nbsp;<span class = "spaceandsize">(non-null)<sup><span class='glossaryLink' onclick="popupDefinition(event, '<b>non-null</b><br>The column cannot contain null values.')">?</span></sup></span>
<br>
<span class="desc">Timestamp when the object was created</span>

<a name="user_createuser"></a>
<p class="column">
<span class="coltitle">CreateUser</span>&nbsp;&nbsp;<span class="titleDesc">foreign key to <A HREF="User.html" TARGET="tableFrame">User</A></span>&nbsp;&nbsp;&nbsp;&nbsp;
<span class = "spaceandsize">(database column: CreateUserID)</span>
<br>
<span class="desc">User who created the object</span>

There are many such Coltitle. titleDesc and desc classes.

Now, if I get an input string like "CreateTime", I want the output to be:

CreateTime, datetime, Timestamp when the object was created

and if I get an input string "CreateUser", I want the output to be:

CreateUser,  foreign key to User, User who created the object

I'm using Jsoup for this, and I have gotten this far:

Elements colElements = Jsoup.parse(html).getElementsByClass("coltitle").select("*");


System.out.println("your Col:");
for (Element element : colElements)
{
    if(element.ownText().equalsIgnoreCase("CreateTime"))
        System.out.println(element.text());
}

which just prints the selected coltitle. How do I parse the related classes and get their values? Or, are they not even related and am I just treading down the wrong path? Can someone please help me get my desired output?

You are only selecting the <span>-tags, thus, only printing what they values they hold.

You can use the siblingElements()-method to get the siblings of the element that you first select.

Your HTML does not seem to be formatted correctly, but the following should work

System.out.println("your Col:");
for (Element element : colElements) {
    if (element.ownText().equalsIgnoreCase("CreateTime")) {
        System.out.print(element.text());
        for (Element sibling : element.siblingElements()) {
            System.out.print(", " + sibling.text());
        }
    }
    if (element.ownText().equalsIgnoreCase("CreateUser")) {
        System.out.print("\n"+element.text());
        for (Element sibling : element.siblingElements()) {
            System.out.print(", " + sibling.text());
        }
    }
}

This will select the elements of the class 'colTitle'. The if-case will check if it's either of them, and then print out the element text. It will then move on to it's siblings, and print out their texts.

According to the api docs, you can call children() on colElements.
