Question

我很难删除XML开头和结尾标签之间以及标签之间的空格。从XML代码中可以看到，标记内有空白，而其他几个封闭符号也有空白

我尝试了对preg_replace（），trim（）的几种修改，但似乎无法使其正常工作。我了解通常，应该拒绝无效的XML而不是尝试对其进行修复，但是我必须对此进行修复。

XML

< priip> 
< data> 
< product> 
< priipCloudProductTemplate>otc</priipCloudProductTemplate> 
< priipCloudProductType>fxSwap</priipCloudProductType> 
< productIdentifier>RBI_fxSwap_EURUSD_long_1Y2D_EUR</productIdentifier> < /product> 
< document> 
< type>final</type> 
< /document> 
< properties> 
< includeEarlyRedemptionInExtraordinaryEventsAlert>true</includeEarlyRedemptionInExtraordinaryEventsAlert> 
< /properties> 
< tradeDate>2018-01-18</tradeDate> 
< effectiveDate>2018-01-20</effectiveDate> 
< fxSwap> 
<holder>client</holder> 
 <currencyPair>EURUSD</currencyPair> 
 <notionalAmount>1000000</notionalAmount> 
 <notionalAmountCurrency>EUR</notionalAmountCurrency> 
 <terminationDate>2019-01-20</terminationDate> 
 <forwardRate> 
 <value>1.25620</value> 
 </forwardRate> .......

我希望输出没有多余的空格

输出XML

<priip> 
<data> 
<product> 
<priipCloudProductTemplate>otc</priipCloudProductTemplate> 
<priipCloudProductType>fxSwap</priipCloudProductType> 
<productIdentifier>RBI_fxSwap_EURUSD_long_1Y2D_EUR</productIdentifier></product> 
<document> 
<type>final</type> 
</document> 
<properties> <includeEarlyRedemptionInExtraordinaryEventsAlert>true</includeEarlyRedemptionInExtraordinaryEventsAlert> 
</properties> 
<tradeDate>2018-01-18</tradeDate> 
<effectiveDate>2018-01-20</effectiveDate> 
<fxSwap> 
<holder>client</holder> 
<currencyPair>EURUSD</currencyPair> 
<notionalAmount>1000000</notionalAmount> 
<notionalAmountCurrency>EUR</notionalAmountCurrency> 
<terminationDate>2019-01-20</terminationDate> 
<forwardRate> 
<value>1.25620</value> 
</forwardRate> ......

Answer 1

也许像这样...

$xml = '< priip>
< data>
< product>
< priipCloudProductTemplate>otc</priipCloudProductTemplate>
< priipCloudProductType>fxSwap</priipCloudProductType>
< productIdentifier>RBI_fxSwap_EURUSD_long_1Y2D_EUR</productIdentifier> < /product>
< document>
< type>final</type>
< /document>
< properties>
< includeEarlyRedemptionInExtraordinaryEventsAlert>true</includeEarlyRedemptionInExtraordinaryEventsAlert>
< /properties>
< tradeDate>2018-01-18</tradeDate>
< effectiveDate>2018-01-20</effectiveDate>
< fxSwap>
<holder>client</holder>
 <currencyPair>EURUSD</currencyPair>
 <notionalAmount>1000000</notionalAmount>
 <notionalAmountCurrency>EUR</notionalAmountCurrency>
 <terminationDate>2019-01-20</terminationDate>
 <forwardRate>
 <value>1.25620</value>
 </forwardRate>';

echo preg_replace('/(<)\s(\/?(?:[A-Z][A-Z\d]*)\b[^>]*>)/i', '$1$2', $xml);

/*
 * Will produce...

<priip>
<data>
<product>
<priipCloudProductTemplate>otc</priipCloudProductTemplate>
<priipCloudProductType>fxSwap</priipCloudProductType>
<productIdentifier>RBI_fxSwap_EURUSD_long_1Y2D_EUR</productIdentifier> </product>
<document>
<type>final</type>
</document>
<properties>
<includeEarlyRedemptionInExtraordinaryEventsAlert>true</includeEarlyRedemptionInExtraordinaryEventsAlert>
</properties>
<tradeDate>2018-01-18</tradeDate>
<effectiveDate>2018-01-20</effectiveDate>
<fxSwap>
<holder>client</holder>
 <currencyPair>EURUSD</currencyPair>
 <notionalAmount>1000000</notionalAmount>
 <notionalAmountCurrency>EUR</notionalAmountCurrency>
 <terminationDate>2019-01-20</terminationDate>
 <forwardRate>
 <value>1.25620</value>
 </forwardRate>
*/

即使标签包含< tag arg="val">之类的属性，标签也可以工作，而其他解决方案不会，不幸的是，由于我的声誉低下，我无法评论他的回答...

我认为它可以帮助您。

<?php

    $xml = <<<XML

    < priip> 
    < data> 
    < product> 
    < priipCloudProductTemplate>otc</priipCloudProductTemplate> 
    < priipCloudProductType>fxSwap</priipCloudProductType> 
    < productIdentifier>RBI_fxSwap_EURUSD_long_1Y2D_EUR</productIdentifier> < /product> 
    < document> 
    < type>final</type> 
    < /document> 
    < properties> 
    < includeEarlyRedemptionInExtraordinaryEventsAlert>true</includeEarlyRedemptionInExtraordinaryEventsAlert> 
    < /properties> 
    < tradeDate>2018-01-18</tradeDate> 
    < effectiveDate>2018-01-20</effectiveDate> 
    < fxSwap> 
    <holder>client</holder> 
     <currencyPair>EURUSD</currencyPair> 
     <notionalAmount>1000000</notionalAmount> 
     <notionalAmountCurrency>EUR</notionalAmountCurrency> 
     <terminationDate>2019-01-20</terminationDate> 
     <forwardRate> 
     <value>1.25620</value> 
     </forwardRate> .......


    XML;

    $x = preg_replace('/(<)(\s+)\/?(\w+\>)/m', "$1$3", $xml);

    echo $x;


    ?>

返回XML

<priipCloudProductType>fxSwap</priipCloudProductType>

您可以使用带有数组映射的简单php private val fSingletonClass来执行操作，以删除带有str_replace()的{{1}}和带有>space的{{1}}
