XSLF Cookbook

XSLF Cookbook +

+ This page offers a short introduction into the XSLF API. More examples can be found in the + XSLF Examples + in the POI SVN repository. +

Please note that XSLF is still in early development and is a subject to incompatible changes in a future release. diff --git a/src/examples/src/org/apache/poi/xslf/usermodel/DataExtraction.java b/src/examples/src/org/apache/poi/xslf/usermodel/DataExtraction.java new file mode 100755 index 0000000000..b7e08fc6f1 --- /dev/null +++ b/src/examples/src/org/apache/poi/xslf/usermodel/DataExtraction.java @@ -0,0 +1,94 @@ +/* + * ==================================================================== + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
