How do we filter the unnecessary knots after the knots with a certain attribute?

[Mystic]

XML file:

<a>
  <Item key="1">
    <c1>
      <d11>
      </d11>
      <d12 value="1" />
      <d13 />
    </c1>
  </Item>
<b2>

<Item key="fix">

<d21>

</d21>

<d22 value="yes" />

<d23 />

</Item>

</b2>
<b3>

<c3>

<d31>

</d31>

<Item key="price">

<e2 value="no" />

<e3 />

</Item>

</c3>

</b3>

</a>

File.xsl:

<xsl:stylesheet version="1.0"

xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="text"/>

<xsl:param name="element-name">Item</xsl:param>
<xsl:template match="/">
&lt;xsl:for-each select="//*[name()=$element-name]"&gt; 

  &lt;xsl:for-each select="ancestor-or-self::*"&gt;

        &lt;xsl:value-of select="name()"/&gt; 

        &lt;xsl:if test="position() != last()"&gt;
            &lt;xsl:text&gt;/&lt;/xsl:text&gt;
        &lt;/xsl:if&gt;
    
        &lt;xsl:if test ="name()=$element-name"&gt;
        &lt;xsl:text&gt;[@key='&lt;/xsl:text&gt;
        &lt;xsl:value-of select="@key"/&gt;
        &lt;xsl:text&gt;']/&lt;/xsl:text&gt;
        &lt;/xsl:if&gt;
    &lt;/xsl:for-each&gt;    
  
        &lt;xsl:for-each select="descendant::*"&gt;

        &lt;xsl:value-of select="name()"/&gt; 

        &lt;xsl:if test="position() != last() and not(@value)"&gt;
            &lt;xsl:text&gt;/&lt;/xsl:text&gt;
        &lt;/xsl:if&gt;
        
        &lt;xsl:if test="(.)[@value]"&gt;
            &lt;xsl:text&gt;/@value&lt;/xsl:text&gt;
        &lt;/xsl:if&gt;
        
        &lt;/xsl:for-each&gt; 
  
    &lt;xsl:text&gt;&amp;#10;&lt;/xsl:text&gt; 
&lt;/xsl:for-each&gt;   

</xsl:template>
</xsl:stylesheet>

After the change, I want to get.

a/Item[@key='1']/c1/d11/d12/@value

a/b2/Item[@key='fix']/d21/d22/@value

a/b3/c3/Item[@key='price']/e2/@value

But it's been made after the transformation:

a/Item[@key='1']/c1/d11/d12/@valued13

a/b2/Item[@key='fix']/d21/d22/@valued23

a/b3/c3/Item[@key='price']/e2/@valuee3

How to filter the unnecessary nodes after the attribution @value?

I just took out the extra code:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text"/>
  <xsl:template match="/">
    <xsl:for-each select="//*[@value]">
      <xsl:for-each select="ancestor-or-self::*">
        <xsl:value-of select="name()"/>
        <xsl:text>/</xsl:text>
      </xsl:for-each>
      <xsl:text>@value&#10;</xsl:text>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

Result:

a/Item/c1/d12/@value
a/b2/Item/d22/@value
a/b3/c3/Item/e2/@value

If necessary, the code that removes the attribute from the component may be returned to the location. Item:

<xsl:if test ="name()='Item'">
  <xsl:text>[@key='</xsl:text>
  <xsl:value-of select="@key"/>
  <xsl:text>']/</xsl:text>
</xsl:if>
