We found a bigger difference for queries that touch a large number of rows, such as a table scan over all 20,000 XML documents with string comparison on every document.
我们发现涉及大量行的查询的性能差异比较大，比如对所有20,000个XML文档进行全表扫描并对每个文档比较字符串。
The root or global space is considered empty and each time the module keyword is encountered during a file scan the string ": :" and the identifiers are appended to the name of the current root.
根或全局空间被认为是空的，文件扫描中每次遇到模块关键字时，字符串“：”和其标识都会附加到当前根的名称后面。
Replacing Spaces with commas and vice versa can be done in a single scan over the string, and the control characters are injected at the same time.
只需对字符串扫描一次，就可以用逗号替换空格，反之亦然，同时还可以加入控制字符。
I get a list of all the content of the element and scan through the list, checking for text (as String objects) and elements.
我获取包含元素所有内容的列表并扫描了这张列表，检查文本(象string对象那样的内容)和元素。

KMP scan algorithm is improved by means of the analysis of string pattern matching BF and KMP. The complexity analysis reveals that the improved algorithm, KMPA, is more effective than KMP.
通过对字符串模式匹配BF和KMP算法的分析，提出了改进KMP扫描算法的方法，并通过对算法的复杂性进行分析，结果表明：改进后的算法KMPA比算法KMP更有效。
It is usually safer to scan a string forward rather than in reverse.
