So, I've been asking a lot of Xpath questions recently.
Sorry, but I've only just started using it, and I'm working on a kind of hard project.
You see, at the moment I'm parsing HTML like this (not a copy and paste, just an example):
<span id="no153434"></span>
<blockquote>Text here.<br/>More text.<br/>Some more text.</blockquote>
And I'm using
//span[starts-with(#id, 'no')]/following::*[1][name()='blockquote']//node()
To get the text inside.
It's working fine, although it's very frustrating. I need to manually check for then manually combine the strings before and after the br, add a newline, and so on. But it stills works. Until there is a link in the text, that is. Then the code is like this:
<span id="no153434"></span>
<blockquote>Text here.<br/>Text.<br/><font class = "unkfunc">linkhere</font></blockquote>
I have absolutely NO idea where to go from here, as the link is included as a completely seperate item (twice) in the array. Atleast with the br I knew where it had to be moved to. Really contemplating giving up in this project after all this effort.
You can use this XPath to obtain text inside element: //span[starts-with(#id, 'no')]/following::*[1][name()='blockquote']//text()
So you receive following result:
Text here.
Text.
linkhere
If you want only text nodes and br:
//span
[starts-with(#id, 'no')]/
following::*[1][name()='blockquote']
//node()
[ count(.|..//text()) = count(..//text())
or
name()='br'
]
returns
Text here.
<br />
Text.
<br />
linkhere
The answer is to not use XPath for this kind of work.
Got it working 1,000,000x easier with Objective-C-HTML-Parser.

First, here is the Typoscript :
20 = TEXT
20 {
value {
field = field_title
wrap = |.txt
}
filelink {
stdWrap.wrap = <li>|</li>
path = fileadmin/txt-files/
}
}
The result I get is :
<li>
<a href="/fileadmin/txt-files/Title.txt">
<img src="typo3/sysext/frontend/Resources/Public/Icons/FileIcons/txt.png">
</a>
</li>
And what I need is :
<li>
<a href="/fileadmin/force_download_script.php?filepath=/fileadmin/txt-files/Title.txt">
<img src="typo3/sysext/frontend/Resources/Public/Icons/FileIcons/txt.png">
</a>
</li>
I need to make the link downloadable, rather than opening the file in the browser. For that I have a force_download_script.php, but when I do that :
wrap = fileadmin/force_download_script.php?filepath=|txt
instead of the current wrap, filelink doesn't find the file anymore.
I have tried using ATagBeforeWrap.wrap but it doesn't look like it's made for that purpose. I also tried typolinkConfiguration.wrap without any success.
Any idea of how to achieve that ? Using a COA maybe ?
Thank you !
I would not do this with a script, but with server configuration. If you use Apache and have .htaccess enabled, you can add the configuration to a .htaccess file in the directory where the files are located. See https://css-tricks.com/snippets/htaccess/force-files-to-download-not-open-in-browser/
Alternatively you can also use the HTML5 download attribute. This is not supported by Internet Explorer however (it is supported by Edge though).
The issue can get quite a bit complicated, but step by step:
your code above might be wrong if it's not just a copy & paste fault:
wrap = fileadmin/force_download_script.php?filepath=|.txt
The dot before txt was missing.
Nevertheless it is still interesting if the php-script is triggered.
It's possible that the script is not triggered due to some settings in typo3conf/LocalConfiguration.php respectively some settings in the install-tool.
Depending on the TYPO3-Version it's also possible that the script is not triggered at all because all scripts are being required now in an extension. That means you might need to create an extension for that script.
Also simple wrapping of the result with the script-path might not be enough, but you have to call it explicitly by TypoScript perhaps by including the script as user-function or lib.
The admin-panel might be useful to debug some things about your script but if not you've to include some debug-output first in your own code, if that's not enough in the core (temporary).
So you've to find out if your script is triggered and if not, the reason for it.
Are you sure .filelink is what you are looking for?
.filelink is for a set of files. For all files in the folder given by .path a link will be generated. see manual
From your description you want a text wrapped with a link to one single file. That would be more a problem for .typolink where you specify the link in .parameter.
if you really want a link list of multiple files, each wrapped with your script you need to modify .typolinkConfiguration.parameter which will be used internaly by .filelink.
Anyway it might be possible to do a wrap which then would be:
.typolinkConfiguration.parameter.wrap = /fileadmin/force_download_script.php?|
Maybe it is easier to build your list with .stdWrap.filelist, where you can use the filenames in any way to wrap your own href parameter for an A-tag.
To use the TYPO3 core solution with file links you can use this guide:
Create a file storage where you want your "secured" files in TYPO3 backend
Do not set the checkbox "Is public?" in the storage record
The links will be rendered with eID and file parameters
You can look into the FileDumpController handling these links: https://github.com/TYPO3/TYPO3.CMS/blob/2348992f8e3045610636666af096911436fa1c89/typo3/sysext/core/Classes/Controller/FileDumpController.php
You can use the included hook to extend this controller with your logic.
Unfortunately I can't find any official documentation for this feature, but will post it when I find something or wrote it myself. ;)
Maybe this can help you, too: https://extensions.typo3.org/extension/fal_securedownload/
Here is the official part, but it's not much: https://docs.typo3.org/typo3cms/CoreApiReference/ApiOverview/Fal/Administration/Storages.html?highlight=filedumpcontroller
I have a problem in FPDF. I want to use MultiCell() to display a text. my code is as follows:
$syarat .='<ol><li>aaa</li>
<li> bbb
<li> ccc</li>
<liddd</li>';
$pdf->SetFont('Arial','',7);
$pdf->SetX(10);
$pdf->MultiCell(190,4,$syarat,0);
//but the problem is it display also with , tags. How to appear numbering instead of , tags?. Thank You
In FPDF did not support the HTML tag ,you have to write it by yourself.
1) if you want to do like this: you can try with HTML->PDF http://html2pdf.fr/
2) You can do with multiple cell Please learn from this exampel
http://www.fpdf.org/en/script/script3.php
If you need help from the example ,Please let me know.
FPDF supports HTML but you need to use a script such as: http://fpdf.org/en/script/script53.php
This one claims that it has full support for lists <li>.
To make the numbers appear, you can always do that manually, for example:
$syarat .='<ul>
<li>1. aaa</li>
<li>2. bbb
<li>3. ccc</li>
<li>4. ddd</li>
</ul>';
Other scripts are available here, but I don't see another one that supports <LI> tags.
I need to find any extra links and print them out. I started by doing:
get_xpath_count('//li/a')
and comparing it to the size of an array that holds the name of all the links for the sidebar. When the count is too high/low, I need to print out all the extra/missing links. I would like to make a list of the names so I can compare it to the array. I've tried a few things like get_text('//li/a'), which returns the name of the first. get_text('//li/a[1]) does the same, but any other index returns nothing.
Any ideas? Also, I need the name that's displayed on the link, not the actual href.
Edit* Also, i'm pretty new to selenium and Xpath. Please let me know if there's info I let out that is needed, or just any suggestions towards thew way I'm going about this.
I have been able to get this to work using CSS element locators. Since I use CSS selectors far more often than Xpath, I find it easier to always use them with Selenium as well.
$selenium->get_text("css=li a:nth-child(1)")
$selenium->get_text("css=li a:nth-child(2)")
$selenium->get_text("css=li a:nth-child(...)")
$selenium->get_text("css=li a:nth-child(n)")
Use:
(//li/a)[$someNumber]
this will get you the text of $someNumber-th //li/a in the XML document.
In order to know what values to use to substitute the $someNumber with, you need to know the total count of these elements:
count(//li/a)
This is in JAVA. You can use the same concept in perl
int totCountInPage=selenium.getXpathCount(//li/a);
for(int count=1;count<=totCountInPage;count++)
System.out.println(selenium.getText("xpath=//li[count]/a"));
This should print text inside the anchor links under all li tag.
I am trying to make a simple paragraph break in my text file (name.js) so that when the iphone pulls the information (name.js) there is not one big run on paragraph. I have looked and looked and cannot find this information can you help me project is due at this time...
try something like this in the javascript:
var pageBreak = document.createElement("/p");
document.getElementsByTagName("tagToInsertBreakAfter")[0].appendChild(pageBreak);
I am away from my machine so i cannot check but try a \n or \r\n
Well it had to be one or the other it'
<br />
i just hacked a widget and tried it. By the way i am assuming you are doing some like the following
// localised strings
var backString_01 = "World Second <br />offers unbeatable exchange rates and exceptional service for foreign exchange and international payments";
then outputting to the document with
document.getElementById('services_headline').innerHTML = backString_01;
With the element in the html something like ....
<div id="services_headline" apple-part="com.apple.Dashcode.part.text" class="apple-text apple-no-children" apple-default-image-visibility="hidden" apple-text-overflow="ellipsis"></div>
I'm currently using Zend_Filter_StripTags in a commenting system, but stuff kinda breaks when '<3' is entered. StripTags doesn't seem to be smart enough to realize that it's not an HTML tag, and creating the filter as "new Zend_Filter_StripTags(array('3'))" doesn't seem to work either.
Should I pass the input through a regexp first, or is there a way to get Zend_Filter_StripTags to straighten up and fly right?
Ended up writing a Zend_Filter class that was basically a wrapper for HTMLPurifier. Works perfectly, because HTMLPurifier is a LOT smarter than striptags.
I'm not familiar with Zend much, but if you want stuff like <3 to be allowed, just do htmlspecialchars instead of strip_tags on it.
What you want is Zend_Filter_HtmlEntites most likely.
See: Zend_Filter_HtmlEnties
The problem with htmlspecialchars and Zend_Filter_HtmlEntities is that if you're trying to strip out all html tags ( like 'a' and 'img', etc ), then instead of stripping them, you end up with that markup in your output.
Take comments on a blog for example. If you use htmlspecialchars or Zend_Filter_HtmlEntities, in a comment where someone tries to use html to enter a link you end up with that markup showing up when you display the comment. But if you use strip_tags or Zend_Filter_StripTags you end up mangling the comment, as neither is smart enough to realize that '<3' isn't a tag, and just strips everything from '<3' until the end of the comment ( or until it finds '>' ).
It would be nice if Zend had something like HTMLPurifier, where it actually checks and validates the input before stripping tags. This means that stuff like '<3' gets left alone, where as stuff like 'Awesome Site' becomes 'Awesome Site'.
This is a problem I'm trying to work around, and at the moment it seems like I'm going to end up writing my own Zend_Filter class that's basically a wrapper for HTMLPurifier.
