quoted string and its quirks

[awalterschulze]

From the spec http:https://www.graphviz.org/content/dot-language

As another aid for readability, dot allows double-quoted strings to span
multiple physical lines using the standard C convention of a backslash
immediately preceding a newline character.

In addition, double-quoted strings can be concatenated using a '+' operator.

Note: < & > are also valid

digraph "0000/addition.slx" {
	"Block#2":out_1->"Block#1":in_1;
	"Block#3":out_1->"Block#1":in_2;
	"Block#1":out_1->"Block#4":in_1;
	subgraph "System#0" {
	"Block#1" [ label=<
    	    <table border="0" cellborder="1" cellspacing="0">
    	        <tr><td port="~" colspan="2">Add</td></tr>
    	        <tr><td port="in_1">in_1</td><td port="out_1">out_1</td></tr>
    	        <tr><td port="in_2">in_2</td><td port="out_2">out_2</td></tr>
    	    </table>
	    >, margin=0, shape=none ];
	"Block#2" [ label=<<table border="0" cellborder="1" cellspacing="0"><tr><td port="~" colspan="2">Constant</td></tr><tr><td port="in_1">in_1</td><td port="out_1">out_1</td></tr></table>>, margin=0, shape=none ];
	"Block#3" [ label=<<table border="0" cellborder="1" cellspacing="0"><tr><td port="~" colspan="2">Constant1</td></tr><tr><td port="in_1">in_1</td><td port="out_1">out_1</td></tr></table>>, margin=0, shape=none ];

}

This looks like a separate issue regarding html parsing, not quoted strings or did I miss something?

[fenollp]

Oh I'm not trying to report an issue, I'm just saying one can apparently use <> for multiline labels.

But now that I think about it, it may only concern HTML labels.
