[英]How to add content to a file, but start from row 4?
I have an xml template that currently looks like this: 我有一个当前看起来像这样的xml模板:
XML: XML:
<?xml version="1.0" encoding="UTF-8"?>
<tv>
<channel id="560"><display-name lang="he">560</display-name></channel>
**** The content I save later will start from line 4 (here) ****
</tv>
My PHP file is dragging content from other files: 我的PHP文件正在从其他文件中拖动内容:
<?php
file_get_contents("http://website.com/guide?1");
file_get_contents("http://website.com/guide?2");
file_get_contents("http://website.com/guide?3");
file_get_contents("http://website.com/guide?4");
file_get_contents("http://website.com/guide?5");
What I want to do is to add the content to the file, 我要做的就是将内容添加到文件中,
But start from line 4 & without deleting the last line 但是从第4行开始且不删除最后一行
UPDATE: 更新:
<tv>
//I want the content to stick to here, before the /tv root
</tv> //Sould be the last line
<channel id="861"><display-name lang="he">861</display-name></channel>

Assuming that your files are also XML compliant, you can do that (otherwise, try to load the remote files using the DOMDocument::loadHTMLFile
method in place of DOMDocument::load
method that is for XML only): 假设您的文件也符合XML,则可以这样做(否则,请尝试使用
DOMDocument::loadHTMLFile
方法代替仅用于XML的DOMDocument::load
方法来加载远程文件):
$dom = new DOMDocument;
$dom->load('template.xml');
$root = $dom->documentElement;
for ($i=1; $i<6; $i++) {
$domi = new DOMDocument;
$domi->load('http://website.com/guide?'.$i);
$rooti = $domi->documentElement;
$node = $dom->importNode($rooti, true);
$root->appendChild($node);
}
$result = $dom->saveXML();
Note that if your remote files are not loaded, you can set stream parameters (in particular the user agent) using libxml_set_streams_context
. 请注意,如果未加载远程文件,则可以使用
libxml_set_streams_context
设置流参数(尤其是用户代理)。
