<h2>Selecting Unknown Nodes</h2>
<p>XPath wildcards can be used to select unknown XML elements.</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table12">
  <tr>
	<td width="20%" valign="top"><b>Wildcard</b></td>
    <td valign="top"><b>Description</b></td>
  </tr>
  <tr>
    <td valign="top">*</td>
    <td valign="top">Matches any element node</td>
    </tr>
  <tr>
    <td valign="top">@*</td>
    <td valign="top">Matches any attribute node</td>
  </tr>
  <tr>
    <td valign="top">node()</td>
    <td valign="top">Matches any node of any kind</td>
    </tr>
  </table>

<h3>Examples</h3>
<p>In the table below we have listed some path expressions and the result of the 
expressions:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table36">
  <tr>
	<td width="30%" valign="top"><b>Path Expression</b></td>
    <td valign="top"><b>Result</b></td>
  </tr>
  <tr>
    <td valign="top">/bookstore/*</td>
    <td valign="top">Selects all the child nodes of the bookstore element</td>
    </tr>
  <tr>
    <td valign="top">//*</td>
    <td valign="top">Selects all elements in the document</td>
    </tr>
  <tr>
    <td valign="top">//title[@*]</td>
    <td valign="top">Selects all title elements which have any attribute</td>
  </tr>
  </table>
<br />

<h2>Selecting Several Paths</h2>
<p>By using the | operator in an XPath expression you can select several paths.</p>

<h3>Examples</h3>
<p>In the table below we have listed some path expressions and the result of the 
expressions:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table37">
  <tr>
	<td width="40%" valign="top"><b>Path Expression</b></td>
    <td valign="top"><b>Result</b></td>
  </tr>
  <tr>
    <td valign="top">//book/title | //book/price</td>
    <td valign="top">Selects all the title AND price elements of all book 
	elements</td>
    </tr>
  <tr>
    <td valign="top">//title | //price</td>
    <td valign="top">Selects all the title AND price elements in the document</td>
    </tr>
  <tr>
    <td valign="top">/bookstore/book/title | //price</td>
    <td valign="top">Selects all the title elements of the book element of the 
	bookstore element AND all the price elements in the document</td>
  </tr>
