AndroidXPath使用多个值获取坐标
我目前正在处理一个kml文件，我在该文件上使用xpath解析器。但是，有些文件与其他文件不同 第一个文件有两种不同的样式：Style1和Style2。然而，在大多数像这样的文件中，style1和style2是不同的链接。我的意思是，下面链接文件中的style1位于其他一些文件style2中。因此，如果我想硬编码它以获得style1，它仍然不能在所有文件上工作 第二个文件只有一种样式，而这个样式工作正常 因此，这些文件的要点是获得具有颜色的样式和具有多个值的坐标（Style2）。但是，我对xPath非常陌生，我不知道如何检查哪个样式具有颜色属性，获取样式值，然后使用该样式属性获取多个坐标。（如果您不理解，请评论，我将尝试以不同的方式解释） 文件一：（这还不起作用）AndroidXPath使用多个值获取坐标,android,xml,xpath,xml-parsing,Android,Xml,Xpath,Xml Parsing,我目前正在处理一个kml文件，我在该文件上使用xpath解析器。但是，有些文件与其他文件不同 第一个文件有两种不同的样式：Style1和Style2。然而，在大多数像这样的文件中，style1和style2是不同的链接。我的意思是，下面链接文件中的style1位于其他一些文件style2中。因此，如果我想硬编码它以获得style1，它仍然不能在所有文件上工作 第二个文件只有一种样式，而这个样式工作正常 因此，这些文件的要点是获得具有颜色的样式和具有多个值的坐标（Style2）。但是，我对xPat
