access the value of attribute (as a variable)

I'm trying to transform my xml file:

<root>
    <group id="F_123" >
        <term id="F_123_d" >
            <word>blabla</word>
            <instruction>blabla</instruction>
        </term>
        <term id="F_123">
            <word>blabla</word>
            <instruction>blabla</instruction>
            <numbers>
                <number code="01" >1</number>
                <number code="02" >2</number>

                <number code="04" >4</number>
                <number code="05" >5</number>
            </numbers>
        </term>
        <term id="F_124">

            </numbers>
        </term>
        <term id="F_125">

            </numbers>
        </term>
    </group>
</root>

I want to access the value of @group/term/@id and make one element per each term in <group id="A_25">. Is it possible?

It's not very clear what exactly do you want, so a guess follows:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:template match="group/term/@id">
    <id>
      <xsl:value-of select="."/>
    </id>
  </xsl:template>

  <xsl:template match="/">
    <root>
      <xsl:apply-templates select="node()" />
    </root>
  </xsl:template>

  <xsl:template match="node()|@*">
    <xsl:apply-templates select="node()|@*" />
  </xsl:template>
</xsl:stylesheet>

When applied to your example (I had to add a root element to it, so that it's valid), it produces:

<root>
  <id>F_123_d</id>
  <id>F_123</id>
  <id>F_124</id>
  <id>F_125</id>
  <id>A_25</id>
  <id>A_26</id>
</root>

I want to access the value of @group/term/@id and make one element per each term in <group id="A_25">. Is it possible?

This XPath expression select what I think you want:

/root/group[@id='A_25']/term/@id 

Also, this stylesheet process what I think you want:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="text()"/>
    <xsl:template match="group[@id='A_25']/term">
        <element id="{@id}"/>
    </xsl:template>
</xsl:stylesheet>

Output:

<element id="A_25" />
<element id="A_26" />
