.SH SYNOPSIS
.LP
.nf
#include <libweb/html.h>
.P
int html_node_set_value(struct html_node *\fIn\fP, const char *\fIval\fP);
.fi

.SH DESCRIPTION
The
.IR html_node_set_value (3)
function sets a value to a
.I struct html_node
object pointed to by
.IR n ,
previously returned by
.IR html_node_alloc (3)
or
.IR html_node_add_child (3).
.I val
is a null-terminated string with the value to be assigned to the node.

.I libweb
allocates a copy of the null-terminated string defined by
.IR val .

As opposed to
.IR html_node_set_value_unescaped (3),
.IR html_node_set_value (3)
escapes characters that could case syntax errors, such as
.B <
.BR "" ( "LESS-THAN SIGN" )
being translated to
.BR &lt; .

.SH RETURN VALUE
On success,
.IR html_node_set_value (3)
returns zero. On failure, a negative integer is returned.

.SH EXAMPLE
A
.I struct html_node
object with
.B example
as tag name and
.B hello
as its value and no attributes would be translated by the HTML
serializer to:

.PP
.in +4n
.EX
<example>hello</example>
.EE
.in
.PP

.SH ERRORS
No errors are defined.
