如何在xpath中将十进制转换为整数？

Question

The input xml includes the following element:

<numberOfPayments>14.0</numberOfPayments>

I need to convert the number to integer, with following limitations:

• the XML is coming from an external source, I cant ask them to send me the integer
• it has to be an XPath, I can't use any other language

Answer 1

You can use round() . The xpath query would be:

round(/numberOfPayments/text())

or if you are only interested in the integer part without rounding you can use floor() :

floor(/numberOfPayments/text())
