Streaming Transformations for XML, kurz STX, ist eine formale Sprache zur Transformation von sehr groΓen XML-Dateien.
STX verbindet das Abstraktionslevel von XSLT mit der Performance von SAX, insbesondere dem niedrigen Speicherbedarf von SAX-Transformationen.

Konzept
STXPath ist speziell fΓΌr die effiziente Verarbeitung sehr groΓer Dateien ausgelegt, und daher weniger ausdrucksstark als XPath. Die XPath-Achsen, die auf Geschwister- und Kindknoten zugreifen, sind in STXPath unbekannt. Die Menge zugelassener PrΓ€dikate ist ebenfalls deutlich kleiner als in XPath. Um trotzdem komplexe Transformationen mit STX ausdrΓΌcken zu kΓΆnnen, ist es erlaubt, den Inhalt von Variablen zu Γ€ndern (im Gegensatz zu XSLT) und ΓΌber diese Variablen den aktuellen Zustand der Transformation auszudrΓΌcken.
