You can parse the XML documents stored in the external file system and store the parsed result either in an Adaptive Server table or in the File Access system.
insert xmlxfsTab(filename , content) select 'parsed'+t.filename,xmlparse(t.content) from xmlxfsTab t ----------- (2 rows affected)
The following code sample queries the parsed documents stored in the XFS file system.
select filename , xmlextract("//book/title" , content)
from xmlxfsTab
where filename like 'parsed%'and filetype = 'REG'
filename
--------------------------------------------
parsedbookstore.1.xml
<title>Seven Years in Trenton</title>
parsedbookstore.2.xml
<title>Modern Database Management</title>
(2 rows affected)
The following code sample uses the xmlrepresentation built-in function to query only the File Access documents that are parsed XML (rather than other sorts of external files):
select filename , xmlextract("//book/title" , content)
from xmlxfsTab
where xmlrepresentation(content) = 0
filename
---------------------------------------
parsedbookstore.1.xml
<title>Seven Years in Trenton</title>
parsedbookstore.2.xml
<title>Modern Database Management</title>
