This is because the expression .//text() yields a collection of text elements – a node-set. And when a node-set is converted to a string, which happens when Scrapy only provides the mechanism; it doesn’t impose any specific organization of your Loaders collection - that’s up to you and your project’s needs. ### 3.6 Scrapy shell The Scrapy shell is an interactive

MON$IO_STATS verwenden ..... 4 Appendices ..... 8 Anhang A: Dokumenthistorie ..... 9 Anhang B: Lizenzhinweis Cache wird immer gefüllt sein. Sie können die MON$-Tabellen (seit Firebird 2.1, insbesondere MON$IO_STATS) nutzen, um herauszufinden, wie gut Ihr Cache ausgelastet ist. Sie zeigen die Anzahl der Fetches gegenüber Sie vermutlich den Cache zu sehr reduziert. ### Kapitel 3. MON$IO_STATS verwenden Wie oben bereits angegeben, kann die Tabelle MON$IO_STATS genutzt werden, um zu bestimmen, wie gut Ihr Buffer-Cache arbeitet
