php - How do I get all of the non excluded items in this list using an XPATH?

Solution:

for the footwear|shoes the XPath may look like

//tags[footwear[not( @exclude='true' )]|shoes[not( @exclude='true' )]]/parent::item
Copy code

This will show 1,2,3

Solution:

This XPath 1.0 expression:

/items/item[
   tags/*[
      not(@exclude='true')
   ][
      contains(
         concat('|',$tags,'|'),
         concat('|',name(),'|')
      )
   ]
]
Copy code

With $tags variable set as'footwear' string selects:

<item>
    <name>Suede Shoe</name>
    <category>Footwear</category>
    <price>£90.00</price>
    <tags>
        <footwear />
        <shoes />
    </tags>
</item>
<item>
    <name>Leather Shoe</name>
    <category>footwear</category>
    <price>£90.00</price>
