How to insert php-statement into html tag ?
I have some html code in my PHP file. For example,
<div id="someId"><div>
I need to insert some PHP group statement into DIV tag:
<div id="someId"><?=SomeClass::getSomeString(); ?><div>
But I can't create PsiElement with text "<?=SomeClass::getSomeString(); ?>" :(
The only way I found:
PhpPsiElementFactory.createPhpPsiFromText(element.getProject(), PhpElementTypes.ANY_GROUP_STATEMENT,"=SomeClass::getSomeString();")
but result looks like this:
<div id="someId"><?php
=SomeClass::getSomeString(); ?><div>
Is there some way to solve this problem?

This is because the string consists of actually 4 PsiElements: an opening tag, an echo statement, a white space, and a closing tag. Let's modify your code a little bit.
Now you only need to find the second opening tag and the second closing tag. After that, you can use PsiElement#addRange* methods to insert a range of elements.
Alternatively, you can use the IntelliJ platform API directly.
PsiFileFactory.getInstance(element.getProject()).createFileFromText("temp.php", PhpFileType.INSTANCE, "<?=SomeClass::getSomeString(); ?>");The previous line will create a new PHP file. It will consist only of your code so it'll be easier to manipulate with it.
I hope I've answered your question. If something is still unclear, feel free to provide us with more details to better understand your needs.
Thanks :)
Yep, the first variant does work...but I've got another problem :)
the code above produces an exception:

The second way works perfectly!
PsiFile tempFile = PsiFileFactory.getInstance(element.getProject()).createFileFromText("temp.php", PhpFileType.INSTANCE, "<?="+stringExp+"?>");PsiElement elementForReplacing = tempFile.getFirstChild();
element.replace(elementForReplacing);// element is innerHTML-content of my div
Well, I had to mention it from the very beginning. In general, it's not a good idea to insert PHP PSI elements into an HTML tree. Instead, you should just put your text directly into a document. It could look something like this (don't forget to commit a document afterward).
