如何使用PHP将许多元素插入DOM

Question

把头发拉出来......

我需要使用PHP在两个不同的点处将一堆html插入到另一组html中.

$ a从另一个类的函数返回给我.我需要在$ a中插入$ b,使$ b元素成为$ a元素的父元素.

<?php
$a = '
<div id="one">
    <div id="two">
        <div id="three">Hi</div>
    </div>
</div> 
';

$b = '
<div id="red">
    <div id="blue"></div>
</div>
<div id="green">
    <div id="yellow">there</div>
</div>
';
?>

需要最终:

<?php
$c = '
<div id="one">
    <div id="two">
        <div id="red">
            <div id="blue">
                <div id="three">Hi</div>
            </div>
        </div>
        <div id="green">
            <div id="yellow">there</div>
        </div>
    </div>
</div>
';
?>

注意如何将$ b插入$ a,使所有$ ba child变为"two".但与此同时,"三"成为"蓝色"的孩子."绿色"和"黄色"保持原有关系,但现在嵌套在"两个"之下.

现实世界的例子......

<?php
$a = '
<div class="ginput_complex ginput_container">
    <span class="ginput_full">
            <input name="input_5" id="input_4_5" type="file" value="" class="medium" tabindex="5">
            <label for="input_4_5" class="ginput_post_image_file">File</label>
    </span>
    <span class="ginput_full ginput_post_image_title">
            <input type="text" name="input_5.1" id="input_4_5_1" value="" tabindex="6">
            <label for="input_4_5_1">Title</label>
    </span>
    <span class="ginput_full ginput_post_image_caption">
            <input type="text" name="input_5.4" id="input_4_5_4" value="" tabindex="7">
            <label for="input_4_5_4">Caption</label>
    </span>
    <span class="ginput_full ginput_post_image_description">
            <input type="text" name="input_5.7" id="input_4_5_7" value="" tabindex="8">
            <label for="input_4_5_7">Description</label>
    </span>
</div>
';


$b =
'
<div class="container">
    <div class="row fileupload-buttonbar">
        <div class="span7">
            <span class="btn btn-success fileinput-button">
            <i class="icon-plus icon-white"></i>

            {{{{{{{{ THIS IS WHERE I MY FILE INPUT SHOULD GO }}}}}}}}}}}

            </span>
            <button type="submit" class="btn btn-primary start">
                <i class="icon-upload icon-white"></i>
                <span>Start upload</span>
            </button>
            <button type="reset" class="btn btn-warning cancel">
                <i class="icon-ban-circle icon-white"></i>
                <span>Cancel upload</span>
            </button>
            <button type="button" class="btn btn-danger delete">
                <i class="icon-trash icon-white"></i>
                <span>Delete</span>
            </button>
        </div>
    </div>
</div>
';

$doc = new DOMDocument;
$doc->loadHTML($a);
$x = new DOMXPath($doc);

?>

我正在使用$ x-> query('//*[@ id ="input_4_5"]')来到我想要开始工作的节点.从那里开始,我一直在使用新的DOMElement和importNode以及appendChild,replaceChild和insertBefore的变体来尝试遍历DOM树.但坦率地说,即使我成功遍历它,我也无法弄清楚如何插入/追加我正在使用的大块代码.

我正在使用SimpleHTMLDom解析器

试试这个:

<?php
require_once( 'simple_html_dom.php' );

$a = '
<div id="one">
    <div id="two">
        <div id="three">Hi</div>
    </div>
</div> 
';

$b = '
<div id="red">
    <div id="blue"></div>
</div>
<div id="green">
    <div id="yellow">there</div>
</div>
';

$a = str_get_html( $a );
$c = str_get_html( $b );

$c->find( 'div[id=blue]', 0 )->innertext = $a->find( 'div[id=two]', 0 )->innertext;
$a->find( 'div[id=two]', 0 )->innertext = $c->save();

echo $a;
?>

希望这可以帮助.
