path expression

This example navigates from Account via two steps to create a path expression representing the name of an account's owner.

The evaluation of a location path expression results in a node-set containing the nodes specified by the location path.

The where clause contains a small path expression that navigates from each address to its nested zip element.

Note that the brace expansion of the file path, not the full remote path expression, has been enclosed in double quotes.

The documents stored in these rows serve as inputs to a path expression that returns all the nested Comment elements.

The same result could be obtained by adding a predicate to the path expression, as shown in Listing 13.

The query shown in Listing 5 could be expressed somewhat more concisely as a three-step path expression, as shown in Listing 7.

As we have seen in the previous chapters, we are selecting and filtering elements with either a Path expression or with a FLWOR expression.

A path expression is the result of navigation from a root expression via one or more persistent attribute(s).

A query on a context node that uses an absolute path expression will start on the root node of the context node .

Hence p. get(Person_. age) denotes a path expression by navigating from the root expression p by the age attribute of Person.

In many cases, it is possible to write a query by using either a FLWOR expression or a path expression.

A path expression in XQuery consists of a series of steps, separated by slash characters.

In the following example, the path expression in the query body does not specify a namespace prefix.

A path expression is similar to a filesystem path.

In this paper, a kind of path expression optimizing principle is proposed by illation, named path shortening method.

To do this simply, use a wildcard (*) in the path expression.

To deal with the tree-like and semi-structured style of XML documents, definitions are given based on path expression.

Note that the path expression is case-sensitive.

Whatever names they use, they all match the path expression based on their substitution group head element.

This is because the path expression in the query targets only elements that have no namespaces.

The problem of low query efficiency based on path expression was well solved with dual index strategy.

p. get(Person_. age) is a path expression.

In addition, any path expression of the URL is ignored.

JET tags requiring a path expression have a select attribute.

The following FLWOR expression will select exactly the same as the path expression above
