XML 个文件的字典

Question

我们有这样一个 XML 字典文件：

<?xml version="1.0" encoding="UTF-8"?>
<words>
    <word>
        <phrase lang="IR">حسابدار</phrase>
        <phrase lang="FR">Comptable</phrase>
        <phrase lang="CN">会计</phrase>
        <phrase lang="US">Accountant</phrase>
    </word>
    <word>
        <phrase lang="IR">حسابرس</phrase>
        <phrase lang="FR">Auditeur</phrase>
        <phrase lang="CN">核数师</phrase>
        <phrase lang="US">Auditor</phrase>
    </word>
    <word>
        <phrase lang="IR">مهندس</phrase>
        <phrase lang="FR">Ingénieur</phrase>
        <phrase lang="CN">工程师</phrase>
        <phrase lang="US">Engineer</phrase>
    </word>
</words>

我们需要一个 PHP 代码来查找包含 "ginee"（工程师）和法语翻译（工程师）的 return 的文本。

我们的PHP代码是

<?php
$xml = simplexml_load_file("test.xml");
$nodes = $xml->xpath('//word/phrase[contains(..,"ngin")]');
var_dump($nodes);
?>

它return

array(4) { [0]=> object(SimpleXMLElement)#2 (2) { ["@attributes"]=> array(1) { ["lang"]=> string(2) "IR" } [0]=> string(10) "مهندس" } [1]=> object(SimpleXMLElement)#3 (2) { ["@attributes"]=> array(1) { ["lang"]=> string(2) "FR" } [0]=> string(10) "Ingénieur" } [2]=> object(SimpleXMLElement)#4 (2) { ["@attributes"]=> array(1) { ["lang"]=> string(2) "CN" } [0]=> string(9) "工程师" } [3]=> object(SimpleXMLElement)#5 (2) { ["@attributes"]=> array(1) { ["lang"]=> string(2) "US" } [0]=> string(8) "Engineer" } }

Answer 1

由于您已经从使用的查询中获得了所需的节点，只需使用 ->attributes():

访问属性（法语 FR）

基本思路：

$nodes = $xml->xpath('//word/phrase[contains(..,"ngin")]');
$lang_needed = 'FR';
$result = '';
if(!empty($nodes)) {
    foreach($nodes as $node) {
        if((string) $node->attributes()->lang === $lang_needed) {
            // $result = (string) $node;
            echo $node;
        }
    }
}

您也可以这样设计查询：

$lang_needed = 'FR';
$nodes = $xml->xpath("//word/phrase[contains(..,'A')][@lang = '{$lang_needed}']");
if(!empty($nodes as $node)) {
    // $result = (string) $node;
    echo $node;
}

Answer 2

这是一个class，将XML解析成一个结构

 class Simple_Parser
{
    var $parser;
    var $error_code;
    var $error_string;
    var $current_line;
    var $current_column;
    var $data = array();
    var $datas = array();

    function parse($data)
    {

        $this->parser = xml_parser_create('UTF-8');
         //UTF-8 encoding geoffers_
        xml_set_object($this->parser, $this);
        xml_parser_set_option($this->parser, XML_OPTION_SKIP_WHITE, 1);
        xml_set_element_handler($this->parser, 'tag_open', 'tag_close');
        xml_set_character_data_handler($this->parser, 'cdata');
        if (!xml_parse($this->parser, $data))
        {
            $this->data = array();
            $this->error_code = xml_get_error_code($this->parser);
            $this->error_string = xml_error_string($this->error_code);
            $this->current_line = xml_get_current_line_number($this->parser);
            $this->current_column = xml_get_current_column_number($this->parser);
        }
        else
        {
            $this->data = $this->data['child'];
        }
        xml_parser_free($this->parser);
    }

    function tag_open($parser, $tag, $attribs)
    {
        $this->data['child'][$tag][] = array('data' => '', 'attribs' => $attribs, 'child' => array());
        $this->datas[] =& $this->data;
        $this->data =& $this->data['child'][$tag][count($this->data['child'][$tag])-1];
    }

    function cdata($parser, $cdata)
    {
        $this->data['data'] .= $cdata;
    }

    function tag_close($parser, $tag)
    {
        $this->data =& $this->datas[count($this->datas)-1];
        array_pop($this->datas);
    }
}
