xml - Copy node and alter its content -

i'm kinda stuck on transformation i'd make on xml file.

basically i'm trying copy xml change tags begins

xml code :

<test alt="foo" title="bar"/> 

what i'd after passing xsl :

<test alt="foo"/> 

or

<change alt="foo" title=""/> 

thing is, got tag lot of attributes, dont want make template match , change every attributes manually.

actually i'm doing :

<xsl:template match="test">     <change><xsl:apply-templates select="@*|node()"/></change> </xsl:template>  <xsl:template match="test/@title">     <xsl:attribute name="title">         <xsl:value-of select=""/>     </xsl:attribute> </xsl:template> 

but doesnt change content of title in output.

for such tasks should start identity transformation template

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

and add templates nodes need special treatment, instance

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

would copy unchanged delete title attributes of test elements.

or

    <xsl:template match="@* | node()">       <xsl:copy>         <xsl:apply-templates select="@* | node()"/>       </xsl:copy>     </xsl:template>  <xsl:template match="test">     <change><xsl:apply-templates select="@*|node()"/></change> </xsl:template>  <xsl:template match="test/@title">     <xsl:attribute name="title"/> </xsl:template> 

should implement second requirement. if still have problems post minimal complete samples allowing reproduce problem.
