What is the full syntax of Groovy's GPath expressions? -

-

While attempting to parse RSS feeds in Groovy, I found a GPath example to use wildcards: 

  deft text = "& table> table name =" person "/> gt; special-tables & gt; other tables & gt; table name =" business "/> And & lt; / other-tables & gt; & lt; / data & gt; "def xml = new XMLPers () .pars (new bytereinterstream (text.getbits ())) def table = EX SML. '**'. Table.find all {this peeper () .name () == "special-table" || it. () .name

(to) < / P>

This looks like a strange use of 'spread-dot' operator. I can not find any reference to Groovy site, books etc.

How it works More importantly, how do you find it? Is there any XPath for GPath 'Rosetta Stone'?

OK, as always, the best place to know Groovy is only in the source to get.
The result of a parsing is a groove.tele slurpersupport.GPathResult object.

If you look at the source (plain Java file), you will see that the getProperty (string) method has the following special operators:

  • ".."
  • "*" which gives to all children
  • "**" which acts as a loop before depth
  • "@ "Which is used to use a property
  • Normal node accessor.

All this, there is no other magic keyword for the moment.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
