Xerces2 na mancie
-----------------

W shellu lub w `~/.bash_profile`

    export CLASSPATH=/usr/share/java2/xercesImpl.jar:/usr/share/java2/xml-apis.jar:.

Rzeczywiście mam nowszą wersję biblioteki Xerces1 niż jest na mancie:

....
## @psi
$ java -classpath /usr/share/java/xerces.jar org.apache.xerces.framework.Version
Xerces 1.4.4
## @manta
$ java -classpath /usr/share/java/xerces.jar org.apache.xerces.framework.Version
Xerces 1.2.3
....

Ale te same wersje Xerces 2

....
## @psi
$ java -classpath /usr/share/java/xercesImpl.jar org.apache.xerces.impl.Version
Xerces-J 2.6.2
## @manta
$ java -classpath /usr/share/java2/xercesImpl.jar org.apache.xerces.impl.Version                   
Xerces-J 2.6.2
....


Przykład
--------

Program dodający do drzewa czytanego ze standardowego wejścia liczby
podane w argumentach przy zachowaniu sortowania i wypisujący
rozszerzone drzewo na standardowe wyjście.

Dla przykładowego wywołania

....
$ echo '<!DOCTYPE root SYSTEM "sorted-tree.dtd">' \
       ' <root value="15" xmlns="http://example.com/sorted-tree"/>' \
     | java SortedTreeExpander 12 7 13 14 7 \
     | java SortedTreeExpander 19 7
....

uzyskujemy na standardowym wyjściu dokument

[xml]
xxxx
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE root SYSTEM "sorted-tree.dtd">
<root value="15" xmlns="http://example.com/sorted-tree">
    <left value="12">
        <left count="3" value="7"/>
        <right value="13">
            <right value="14"/>
        </right>
    </left>
    <right value="19"/>
</root>
xxxx

opisany schematem link:sorted-tree.xsd[]:

htmlize::sorted-tree.xsd[]

oraz link:sorted-tree.dtd[]:

htmlize::sorted-tree.dtd[]

Program ma postać link:pub/SortedTreeExpander.java[]:

htmlize::pub/SortedTreeExpander.java[]

// htmlize::SortedTreeExpander2.java[]
