How to use double quotes in xml?

Question

I use QT's QDomDocument. There is a problem when using QDomDocument::setContent(), the compiler complains at this line:

< field regexp = "text".+"text" >

I tried so:

Why don't you just use a [raw string literal](https://en.cppreference.com/w/cpp/language/string_literal) (variant 6 on that page)? — Jesper Juhl, Jun 02 '20 at 19:44

XML attribute values can be delimited by ', which is useful when the attribute value must contain a ".

So, if the attribute value in intended to be, say, text".+"text, use:

<field regexp='text".+"text'>

Alternatively, " can be used for ".

<field regexp="text&quot;.+&quot;text">

@JesperJuhl: I'd only addressed the XML well-formedness concerns. Thanks for adding the suggestion regarding string formation for the C++ function argument, which indeed has to be satisfied first. – kjhughes Jun 02 '20 at 22:07
