XPath select certain amount of levels only -

-

if have xml structure this

 <root>   <sub>     <node />     <node />   </sub>     <sub>       <node />     <sub>   <sub>     <sub>       <node />     </sub>   </sub>   <sub>     <sub>       <sub>         <node />       </sub>       <node />     </sub>   </sub>   <node />   <node /> </root>

is there xpath syntax select first 3 levels of nodes?

so collect

 <root>   <sub>     <node />     <node />   </sub>     <sub />   <sub>     <sub />   </sub>   <sub>     <sub />   </sub>   <node />   <node /> </root>

update

just explain i'm doing, i've got asp:treeview, binding asp:xmldatasource, , want tree view go 3 nodes deep. may possible on treeview or xmldatasource control way, xpath seemed obvious

thanks, psy

you can add rule matches below level "does nothing": 

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

so complete example:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" version="1.0">   <xsl:output indent="yes"/>   <xsl:template match="node() | @*">     <xsl:copy>       <xsl:apply-templates select="node() | @*"/>     </xsl:copy>   </xsl:template>     <xsl:template match="/*/*/*/*"/>  </xsl:stylesheet>

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
