使用PHP解析KML文件 [英] Parse KML file with PHP

问题描述

是否可以使用simple_xml_load_file("*.kml")解析Google Maps * .kml文件?

Is there a way to parse google maps *.kml file with simple_xml_load_file("*.kml") ?

我需要在数据库中保存我的KML文件中注册的每个多边形的名称和坐标. 在我的PHP脚本中，simple_xml_load_file("*.kml")返回false，因此无法读取.

I need to save in my database name and coordinates of each polygons registered in my KML file. On my PHP script, simple_xml_load_file("*.kml") return false, so I can't read it.

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">
    <Document>
        <Schema>
        ...
        </Schema>
        <Style id="FEATURES">
        ...
        </Style>
        <Folder>
            <Placemark>
                <name>
                    name
                </name>
                <Polygon>
                    <LinearRing>
                        <coordinates>
                            coordinates
                        </coordinates>
                    </LinearRing>
                </Polygon>
            </Placemark>
            <Placemark>
                ...
            </Placemark>
        </Folder>
    </Document>
</kml>

每个地标"都需要名称"和坐标"值.

I need "name" and "coordinates" values for each "Placemark".

推荐答案

第一行:

<?xml version="1.0" encoding="UTF-8"?>

告诉PHP这是一个使用UTF-8编码的文档，但是您的错误表明它未编码为UTF-8.这是您使用文本编辑器创建的文档吗?如果是这样，通常可以使用编辑器将其保存在UTF-8中.或者，您可能可以使用PHP来检测编码并更改第一行.

Tells PHP that this is a document encoded in UTF-8, but your error says it is not encoded as UTF-8. Is this a doc you created with a text editor? If so, you can usually use your editor to save it out in UTF-8. Or you can probably use PHP to detect the encoding and change that first line.
