  i want:-

我想在文本框中输入纬度和经度值，如果两者在我的xml文件中匹配则返回兄弟节点值。

problem:-

我不知道如果根元素具有属性值
是什么问题  比如<results xmlns="http://gisgraphy.com">它不起作用  如果删除此属性值，那么工作完美...
任何想法，这对我的食物帮助...
感谢

你需要一个稍微不同的xpath，其中“result”有一个前缀，然后使用命名空间解析器作为evaluate函数的第三个参数。请参阅https://developer.mozilla.org/en-US/docs/Introduction_to_using_XPath_in_JavaScript#Implementing_a_User_Defined_Namespace_Resolver以获取有关如何执行此操作的说明和示例。

xslt4convert： - 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:output method="xml" version="1.0" encoding="UTF-8" />
        <xsl:template match="*">
                <xsl:element name="{local-name()}">
                        <xsl:apply-templates select="@* | node()"/>
                </xsl:element>
        </xsl:template>
</xsl:stylesheet>

创建一个php文件来加载xml和xslt文件： - 

<?php
$sourcedoc = new DOMDocument();
    $sourcedoc->load('filename.xml');
    $stylesheet = new DOMDocument();
    $stylesheet->load('new4convert.xsl');
     // create a new XSLT processor and load the stylesheet
    $xsltprocessor = new XSLTProcessor();
    $xsltprocessor->importStylesheet($stylesheet);

    // save the new xml file
    file_put_contents('filename.xml', $xsltprocessor->transformToXML($sourcedoc));
?>

它的声音是返回这种类型的xml文件： - 

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

        <result>
