XPath - Nodo de texto

El texto se puede recuperar y verificar fácilmente usando el nombre del elemento.

name - obtener el valor de texto del nodo "nombre".

<td><xsl:value-of select = "firstname"/></td>

El texto se puede utilizar para comparar utilizando operadores.

marks > 85 - obtener el valor de texto de las "marcas" del nodo y compararlo con un valor.

<xsl:if test = "marks > 85">

Ejemplo

En este ejemplo, creamos un documento XML de muestra students.xml y su documento de hoja de estilo students.xsl que usa las expresiones XPath.

A continuación se muestra el XML de muestra utilizado.

estudiantes.xml

<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "students.xsl"?>
<class>
   <student rollno = "393">
      <firstname>Dinkar</firstname>
      <lastname>Kad</lastname>
      <nickname>Dinkar</nickname>
      <marks>85</marks>
   </student>
   <student rollno = "493">
      <firstname>Vaneet</firstname>
      <lastname>Gupta</lastname>
      <nickname>Vinni</nickname>
      <marks>95</marks>
   </student>
   <student rollno = "593">
      <firstname>Jasvir</firstname>
      <lastname>Singh</lastname>
      <nickname>Jazz</nickname>
      <marks>90</marks>
   </student>
</class>
