Question

我有这种类型的xml文件调用是regin.xml： -

<root>
  <child_1 entity_id = "1" value="Game" parent_id="0">
    <child_2 entity_id="2" value="Activities" parent_id="1">
      <child_3 entity_id="3" value="Physical1" parent_id="2">
        <child_6 entity_id="6" value="Cricket" parent_id="3">
          <child_7 entity_id="7" value="One Day" parent_id="6"/>
        </child_6>
      </child_3>
      <child_4 entity_id="4" value="Test1" parent_id="1">
        <child_8 entity_id="8" value="Test At Abc" parent_id="4"/>
      </child_4>
      <child_5 entity_id="5" value="Test2" parent_id="1">
        <child_9 entity_id="9" value="Test At Xyz" parent_id="5"/>
      </child_5>
    </child_2>
</child_1>
</root>

这是一个字符串： -

$activity = "One Day,Test At Abc,Test At Xyz";

这里我想在xml文件中逐个检查单独的值检查我试试这个xpath。

$Rgn_id = $region->xpath("//*[@value = '$region1']/@entity_id");

如果活动在xml文件中匹配，则在xml文件中显示entity_id 感谢...

这是我的php尝试： -

<?php
$Activity = 'One Day,Test At Abc';
echo "$Activity";
$string = explode(",",$Activity);
echo "<pre>";
print_r ($string);
echo "</pre>";
$r = file_get_contents('final.xml');
$region = simplexml_load_string($r);
foreach($string as $Activity){
list($result) = $region->xpath("//*[contains('$Activity', (@value ,','))]/@entity_id");
$result = (string)$result;
echo "my activity id is = $result";
 }
?>

Answer 1

您可以使用

$value = ",$activity,"; // now $value is ",One Day,Test At Abc,Test At Xyz,"

$Rgn_id = $region->xpath("//*[contains('$value', concat(',', @value, ','))]/@entity_id");

Answer 2

使用：

//*[contains(concat(',', $activity, ','), concat(',', @value, ','))]/@entity_id

基于XSLT的验证：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:variable name="activity" select="'One Day,Test At Abc,Test At Xyz'"/> <xsl:template match="/"> <xsl:variable name="vWanted" select= "//*[contains(concat(',', $activity, ','), concat(',', @value, ',') ) ]/@entity_id"/> <xsl:for-each select="$vWanted"> <xsl:value-of select="concat(., ' ')"/> </xsl:for-each> </xsl:template> </xsl:stylesheet>

在提供的XML文档上应用此转换时：

<root> <child_1 entity_id = "1" value="Game" parent_id="0"> <child_2 entity_id="2" value="Activities" parent_id="1"> <child_3 entity_id="3" value="Physical1" parent_id="2"> <child_6 entity_id="6" value="Cricket" parent_id="3"> <child_7 entity_id="7" value="One Day" parent_id="6"/> </child_6> </child_3> <child_4 entity_id="4" value="Test1" parent_id="1"> <child_8 entity_id="8" value="Test At Abc" parent_id="4"/> </child_4> <child_5 entity_id="5" value="Test2" parent_id="1"> <child_9 entity_id="9" value="Test At Xyz" parent_id="5"/> </child_5> </child_2> </child_1> </root>

评估XPath表达式，然后输出作为此评估结果选择的属性值：

7 8 9

在xml文件中使用逗号分隔检查字符串值
