Question

how can I add a string in an empty font tag? Like if in the second font tag there is no value, I will just insert a <br /> tag. How can I do that?

I have this HTML code:

<P ALIGN="LEFT">
    <FONT FACE="Verdana" style="font-size:10" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">
        Welcome to jQuery Course
    </FONT>
</P>
<P ALIGN="LEFT">
    <FONT FACE="Verdana" style="font-size:10" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">
    </FONT>
</P>
<P ALIGN="LEFT">
    <FONT FACE="Verdana" style="font-size:10" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">
        This is the jQuery Introduction content.
    </FONT>
</P>

And I like the output to be:

<P ALIGN="LEFT">
        <FONT FACE="Verdana" style="font-size:10" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">
            Welcome to jQuery Course
        </FONT>
    </P>
    <P ALIGN="LEFT">
        <FONT FACE="Verdana" style="font-size:10" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">
            <br />
        </FONT>
    </P>
    <P ALIGN="LEFT">
        <FONT FACE="Verdana" style="font-size:10" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">
            This is the jQuery Introduction content.
        </FONT>
    </P>

Answer 1

You shouldn’t be using a font tag.

You can

str_replace("></FONT>", ">$myinserttext</FONT>", $myhtml);

in PHP or

$("font:empty").html("Sample Content");

in jQuery.
