我很想知道,是否可以使用XPath或XSL来确定XML的负值是数字还是字母/数字。 (用户输入数据,也可以输入数据。)
我正在XPath寻求某种功能,以便做到这一点,但我无法找到。
例如:
<example>
<test1 attribute="123">12dfffg23</test1>
<test2 attribute="a34">123456</test2>
</example>
我需要测试诺言的内容和内容:
/example/test1
/example/test1/@attribute
/example/test2
/example/test2/@attribute
我预计数字如下:
/example/test1/@attribute
/example/test2
我预计以下是字母/数字:
/example/test1
/example/test2/@attribute
是否可能用XPath或XSL的功能来做到这一点?
感谢!
www.un.org/Depts/DGACM/index_spanish.htm 在XPath 1.0中,用于检验某一方的载体是否含有编号:
number(someString) = number(someString)
www.un.org/Depts/DGACM/index_spanish.htm 用于测试某一方体是否仅由字母或数字构成:
not(translate(someString, $alphabetLowerAndUpperAndDigits, ))
字母缩略语
<>XPath 2.0: (以上各段加)
matches(someString, ^[c|d]+$ )
