XSL can't use template match

I try for first time xsl, and in 3 hour can't print a single line!

btw. MOST simple xml file:

 <?xml version="1.0" encoding="UTF-8"?>

<book>
    <author>qqqqqq</author>
    <title>Srwrtwt</title>
    <title>yoo</title>
    <price>$10.00</price>
</book>

And one version of xsl:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="html"/>

    <xsl:template match="author">
        <html>

        </html>
    </xsl:template>

    <xsl:template match="title">
            <h1>
            <xsl:apply-templates/>
            </h1>   
    </xsl:template>

</xsl:stylesheet>

The output is:

    <html></html>
    <h1>Srwrtwt</h1>
    <h1>yoo</h1>
    $10.00

And I'm ok with that, BUT if i change the xsl like this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="html"/>

    <xsl:template match="/">
        <html>

        </html>
    </xsl:template>

    <xsl:template match="title">
            <h1>
            <xsl:apply-templates/>
            </h1>   
    </xsl:template>

</xsl:stylesheet>

This is the output, why template match="title" NOW does not work?:

<html></html>

The fact is that I have done similar example to try to understand why this happens and in other cases it works: example:

<?xml version="1.0"?>
<page>
    <title>Hello World</title>
    <content>
        <x>dewjnf</x>
        <paragraph>
            <resume>This is my first page!</resume>
        </paragraph>
    </content>
</page>

the xsl:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="html" />
    <xsl:template match="/">
        <html>
            <head>
                <title>
                    <xsl:value-of select="page/title" />
                </title>
                <style>
                    h1{
                    color: blue;
                    font-style: italic;
                    }
                </style>
            </head>
            <body>
                <xsl:apply-templates />
            </body>
        </html>
    </xsl:template>

    <xsl:template match="title">
        <div align="center">
            <h1>
                <xsl:value-of select="." />
            </h1>
        </div>
    </xsl:template>
    <xsl:template match="resume">
        <p>
            <xsl:apply-templates />
        </p>
    </xsl:template>
</xsl:stylesheet>

And the output is exactly what I expected with the template match working: To me seems exactly the same thing of the previous example but with different behave.

<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello World</title>
<style>
h1 {
    color: blue;
    font-style: italic;
}
</style>
</head>
<body>

    <div align="center">
        <h1>Hello World</h1>
    </div>

    dewjnf

    <p>This is my first page!</p>



</body>
</html>

The question is why sometimes when there is match="/" the others matches does not work and sometimes yes? where is the error?

Why does the title template not work in the second example? Because it is not reached. You should do an <xsl:apply-templates/> inside the <xsl:template match="/"/><html>... - it won't recurse by itself

If you like to have more matches you need to add 

<xsl:apply-templates />

in your templates. If you don't the child nodes will not considered.
