Recipe #3Cook’n up some XML
Why is XML so difficult?
XML is really a language
The language describes the data structures as well as the data content
XML folks seem to revel in complex data structures
Hierarchical data structures
GIS systems are usually based on relational data models
FME & XML
You need to tell FME how to interpret the XML data structures.
Reading XML
Options for Reading XML with FME
GML 3.2 & XSD
Most GML can be interpreted if FME can use the XSD
This will work if the OGC spec. is followed and internal feature constructs are not overly complex.
Xfmap
Proprietary script for mapping XML structure to FME features
Xquery
W3C compliant Xquery
Map XML tags to features or attributes using XQueryExploder & XQueryExtractor
27
Writing XML
Options for Writing XML with FME
GML standard formats
FME supports a wide range of GML profiles (GML SF0, OS MasterMap, etc.)
GML 3.2 & XSLT
Apply an XSLT (Extensible Stylesheet LanguageTransformations) to the output
Xquery
W3C compliant Xquery
Map FME features to XML templates using XMLTemplater transformer
28
XML Transformers
Reading
XQueryExploder
Split XML documents into manageable “features”
XQueryExtractor
Extract attributes and other structures
Writing
XMLTemplator
Convert FME attributes to XML
Transformation
XSLTProcessor
29
Example: XML Object hierarchy
Creating an electricsubstation XML:
Coordinates
and
Attributes
and contains
Feeder(s) contain
Attributes
XML Document
Substation
Feeder A
Feeder B
Example
Sample XML: Source of XML
templates
Add Xquery: replace attribute values with Xquery statements
Sample XML <substation objectID="Vancouver Substation">
<mapLocation>
<coord>
<X>669170.169</X>
<Y>1000199.534</Y>
</coord>
</mapLocation>
<facilityID>5E67B377</facilityID>
<sectionID>RPG123</sectionID>
<phaseCode>ABC</phaseCode>
<feederList>
<feederObject objectID="8-64">
<feederName>10-24</feederName>
<feederNo>8763</feederNo>
<eaLoc>9D2D</eaLoc>
</feederObject>
<feederObject objectID="8-65">
<feederName>10-25</feederName>
<feederNo>8766</feederNo>
<eaLoc>9D3F</eaLoc>
</feederObject>
</feederList>
<name>Vancouver Central</name>
</substation>
<feederObject objectID="{fme:get-attribute("objectID")}">
<feederName>{fme:get-attribute("feederName")}</feederName>
<feederNo>{fme:get-attribute("feederNo")}</feederNo>
<eaLoc>{fme:get-attribute("eaLoc")}</eaLoc>
</feederObject>
Recipe #4Add a Dash of Update to Your Database
Dump and Reload Tables (Or Whole Databases)
or
Update Individual Rows
Database Update Options
Use fme_db_operation format attribute
Feature Level Updates
FME 2010:
Joiner
SQLExecutor
ArcSDEQuerier
OracleQuerier
FME 2011 adds:
FeatureReader
SQLQuerier
SQLCreator
Database Transformers
Database Update Example
Update Address Points for selected Zip Code boundaries
Read the Zip Codes
Spatial query for the Address Point updates (based on the zip code boundary)
Create the fme_db_operation attribute
Write to database with insert | update | delete
Recipe #5Schema Mapper!
Schema Mapper
Move the intelligence of attribute and feature type mapping out of the workspace
Very powerful in combination with Dynamic Workspaces
Makes workspaces easier to maintain!
