如何使用XML :: Writer perl插入XML(How to insert XML using XML::Writer perl)

 我试图建立一个可以根据输入的内容动态创建xml的系统。 我有一个总是相同的seleton，并且唯一需要动态创建的是formfields。 因此，例如，我需要将$ testXML插入到我的$ writer XML中。 这是我到目前为止所拥有的 
 

use strict;
use warnings;
use XML::Writer;
my $test = XML::Writer->new(OUTPUT => 'self', DATA_MODE => 1, DATA_INDENT => 2, );
$test->startTag('FormField', name => 'CheckBox1');
$test->startTag('Value');
$test->characters('');
$test->endTag('Value');
$test->endTag('FormField');
my $testXML = $test->end();

 

 插入 
 

my $writer = XML::Writer->new(OUTPUT => 'self', DATA_MODE => 1,           DATA_INDENT => 2, );
$writer->startTag('Section', name => 'FormSectionOne');
$writer->startTag('FormField', name => 'Person1');
$writer->startTag('Value');
$writer->characters('Bob Test');
$writer->endTag('Value');
$writer->endTag('FormField');
$testXML;
my $xml = $writer->end();
print $xml;

 

 现在使用$ writer-> raw（$ testXML）; 插入，但格式有问题 
 

 <Section name="FormSectionOne">
      <FormField name="Person1">
        <Value>Bob Test</Value>
      </FormField><FormField name="CheckBox1">
  <Value>test</Value>

 


Im trying to make a system that can dynamically create xml based on what is entered. I have a seleton that will always be the same, and the only thing that need to be created dynamically is the formfields. So for example, I need to insert $testXML into my $writer XML. Here is what I have so far 
 

use strict;
use warnings;
use XML::Writer;
my $test = XML::Writer->new(OUTPUT => 'self', DATA_MODE => 1, DATA_INDENT => 2, );
$test->startTag('FormField', name => 'CheckBox1');
$test->startTag('Value');
$test->characters('');
$test->endTag('Value');
$test->endTag('FormField');
my $testXML = $test->end();

 

Inserted into 
 

my $writer = XML::Writer->new(OUTPUT => 'self', DATA_MODE => 1,           DATA_INDENT => 2, );
$writer->startTag('Section', name => 'FormSectionOne');
$writer->startTag('FormField', name => 'Person1');
$writer->startTag('Value');
$writer->characters('Bob Test');
$writer->endTag('Value');
$writer->endTag('FormField');
$testXML;
my $xml = $writer->end();
print $xml;

 

Now using $writer->raw($testXML); inserts but the formatting has problems
 

 <Section name="FormSectionOne">
      <FormField name="Person1">
        <Value>Bob Test</Value>
      </FormField><FormField name="CheckBox1">
  <Value>test</Value>

 您可以找到value="0"的元素的数量，并将其与总计数进行比较以hide()与类points__fees最接近的元素： 
 

 

 
 
 
  
var count = $('.points__fees__input[value="0"]').filter(function(){
  return this.value === "0";
}).get();
if($('.points__fees__input[value]').length == count.length)
  $('.points__fees__input[value="0"]').closest('.points__fees').hide();
 
  
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="points__fees">
    <div class="points__fees__label">Fees / Charges</div>
    <div class="points__fees__value">
        <div class="points__fees__value__item" data-type="star$">
            <span class="points__fees__text">0</span> Star $
            <input class="points__fees__input" value="0" type="hidden">
        </div>
        <div class="points__fees__value__item" data-type="diamond$">
            <span class="points__fees__text">0</span> Diamond $
            <input class="points__fees__input" value="0" type="hidden">
        </div>
        <div class="points__fees__value__item" data-type="gold$">
            <span class="points__fees__text">0</span> Gold $
            <input class="points__fees__input" value="0" type="hidden">
        </div>
    </div>
</div>
 
 
 

 


You can find the count of elements with value="0" and compare that with total count to hide() the closest element with class points__fees:
 

 

 
 
 
  
var count = $('.points__fees__input[value="0"]').filter(function(){
  return this.value === "0";
}).get();
if($('.points__fees__input[value]').length == count.length)
  $('.points__fees__input[value="0"]').closest('.points__fees').hide();
 
  
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="points__fees">
    <div class="points__fees__label">Fees / Charges</div>
    <div class="points__fees__value">
        <div class="points__fees__value__item" data-type="star$">
            <span class="points__fees__text">0</span> Star $
            <input class="points__fees__input" value="0" type="hidden">
        </div>
        <div class="points__fees__value__item" data-type="diamond$">
            <span class="points__fees__text">0</span> Diamond $
            <input class="points__fees__input" value="0" type="hidden">
        </div>
        <div class="points__fees__value__item" data-type="gold$">
            <span class="points__fees__text">0</span> Gold $
            <input class="points__fees__input" value="0" type="hidden">
        </div>
    </div>
</div>
