search condition

Dear people,
forgive me if my question is very basic.

<root>
<children>
  <textid>ABC</textid>
</children>
<children>
  <textid>DEF</textid>
</children>
<children>
  <textid>ABC</textid>
</children>
<children>
  <textid>FGH</textid>
</children>
<children>
  <textid>ABC</textid>
</children>
</root>

please correct me if i am wrong
i am writing the xsl like below

<xsl:for-each select="//root/children/textid[.='ABC']">
<!-- to print the text -->
<xsl:value-of select="."/>
</xsl:for-each>

many thanks in advance
laura
