How to use Substitute() on special character like " and '

Here I want to substute site address in every <img> tag <img src="/Test/Test.jpg" alt="" />

so I use

Substitute(ThisItem.Instructions,"<img src=","<img src='https://powerTest.sharepoint.com")

But here it breaks a URL by adding extra "

Result: <img src="https://powerTest.sharepoint.com"/Test/Test.jpg" alt="" />

 

So images are not render in Htmltext control.  If anyone have idea please suggest how to do this?

Hi @HirenKataria,

Based on the needs that you mentioned, I agree with @NEPatton's thought almost. I think the Char() function could achieve your needs.

On your side, please modify your Substitude formula as below:

Substitute(
ThisItem.Instructions,
"<img src="&Char(39),
"<img src="& Char(39) &"https://powerTest.sharepoint.com"
)

More details about the Char() function in PowerApps, please check the following article:

You can use the following expression:

Substitute(
    ThisItem.Instructions,
    "<img src=""",
    "<img src=""https://powertest.sharepoint.com")

This will search for the (") character (to enter a double quote in a string you need to "double it"), and replace it with another one.

Yeah - the root of the issue here is that you were searching/replacing

<img src=

but you really wanted to be searching for

<img src="

 

You can follow @CarlosFigueira's method, or you can use the Char() function.  The Char() function can sometimes look clunky, but I often prefer it because there are fewer questions about what's happening.  Char(34) = "  It's equivalent to write Char(34) as it is to write "".  Using this function, your solution could also look like this:

 

Substitute(
    ThisItem.Instructions,
    "<img src="&char(34),
    "<img src=""https://powertest.sharepoint.com")

 Or, alternatively....

Substitute(
    ThisItem.Instructions,
    "<img src="&char(34),
    "<img src="&char(34)&"https://powertest.sharepoint.com")

 

So again -- it looks clunky, but if you're comfortable with using functions like this -- it could be argued that there is less ambiguity here.  2 ways to get the same thing, pick your preference and good luck!
