Path Section Searching

XML documents can have parent-child tag structures such as:

<A> <B> <C> dog </C> </B> </A>

In this scenario, tag C is a child of tag B which is a child of tag A.

With Oracle Text, you can do path searching with PATH_SECTION_GROUP. This section group enables you to specify direct parentage in queries, such as to find all documents that contain the term dog in element C which is a child of element B and so on.

With PATH_SECTION_GROUP, you can also perform attribute value searching and attribute equality testing.

The new operators associated with this feature are

• INPATH

• HASPATH

This section contains the following topics.

• Creating an Index with PATH_SECTION_GROUP

• Top-Level Tag Searching

• Any-Level Tag Searching

• Direct Parentage Searching

• Tag Value Testing

• Attribute Searching

• Attribute Value Testing

• Path Testing

• Section Equality Testing with HASPATH
