Why can't extract data with xidel?

Display content in books.xml.

cat  books.xml
<?xml version="1.0" encoding="UTF-8"?>
<books>   
   <book category="JAVA">
      <title lang="en">Learn Java in 24 Hours</title>
      <author>Robert</author>
      <year>2005</year>
      <price>32.00</price>
   </book>
   <book category="XML">
      <title lang="en">Learn XPath in 24 hours</title>
      <author>Jay Ban</author>
      <year>2010</year>
      <price>16.50</price>
   </book>   
</books>

The xquery string:

xstring='''
for $x in doc("books.xml")/books/book
where $x/price>30
return $x/title'''

Why can't extract the book title whose price is larger than 30 with xidel?

Both where $x/price>30 and where $x/price/text)>30 can't take effect.

Solution

  • Assuming your xml is stored in file.xml, this should work:

    xidel file.xml --xquery 'for $x in //book where $x/price/text() gt 30 return $x/title'

    My output:
