Parse HTML Without Xpath?

I'm trying to create a simple tool to parse html files.

Specifically, I need it to get all the name attributes out of all the div tags.

My HTML string varies and I don't have any control over it, so if I try and use xpath I tend to get errors as the HTML is not 100% written correctly.

Comparing Form Fields With Data Base Fields And Highlighting The Form Fields?

the following two scenarios (PHP+MYSQL)

Scenario1: I need to compare the HTML Form field values with the Database field values and highlight the form fields in some color whose values are different from database values before submitting the form (to alert the user).

Scenario2: On loading the form, i need to compare the values present in 2 different database tables (tables are having different column names but the information is same). the fields which are not same needs to be highlighted in the html form to indicate the users that the master data is varying from secondary data.

Reading Xml: Can Xpath Read 2 Fields?

I'm using SimpleXMLElement and xpath to try and read the <subcategory><name> from the xml at the very bottom. This code works.. but the stuff inside the while loop looks a little messy, and now I also want to get the <subcategory><count> and somehow pair it with its appropriate <subcategory><name>.

$names = $xml->xpath('/theroot/category/subcategories/subcategory/name/');
while(list( , $node) = each($names)) {
echo $node;

My question: Is it possible to get this pairing while still using xpath since it looks like it can make the job easier?

<name>Category 1</name>[code]....

Regex - Parse HTML With XPath

Is there a way (using XPath and PHP) to do the following (WITHOUT external XSLT files)? Remove all tables and their contents Remove everything after the first h1 tag Keep only paragraphs (INCLUDING their inner HTML (links, lists, etc)) I received an XSLT answer here, but I'm looking for XPATH queries that don't require external files. Currently, I've got the HTML in question loaded into a SimpleXmlElement via:

$doc = @DOMDocument::loadHTML($xml);
$data = simplexml_import_dom($doc);

Now I need help with:

$data = $data->xpath('??????');

Been working with this one for several days to no avail. Edit: I don't particularly care what's inside the paragraphs, as I can use strip_tags to eliminate what I don't want. All I need to do is to isolate the paragraphs from the rest of the source. I suppose a more specific, accurate requirement would be this: Return only paragraphs (and their html contents) that aren't contained in tables, and only before the first h1 tag Edit 2: I think I've gotten most of it with this:

$query = $xpath->query('//p[not(ancestor::table) and not(preceding::h2)]');

The only problem is the loss of the inner HTML.

Parse Html With Xpath Without SimpleXML

I have been wrecking my brain trying to figure out how to use xpath, alone, to parse html code. A conscious effort was made to learn xpath to the exclusion of simplexml, because; simplexml is quite limited, IMHO based on my research. Given the following sample html code how


I am clueless on what to do from this point on to parse the Auto make, auto models and website links. What is a example of how to parse the values of nodes and sub nodes, using xpath alone?

Basic Html Form The Input Fields Be Inside Can Fill Those Fields With Data And Submit Them To A Database?

Bare with me here.New to ajax.What I would like to do is have a basic html form the input fields be inside php so that you can fill those fields with data and submit them to a database.Once that data exists in the database I want that data to fill the input fields.I want all this to be done in java/ajax/php so my page never refreshes.But I can submit data to a MYSQL database and retrieve from it.Example code of this would be best so I can see it and learn it.

Right now I have seen how to pull from a database and fill input with the data without page refresh.Also I have seen how to enter data into a database without the page refresh.I can't find and example of both combined.

Use JQuery To Add Form Fields And Sessions To Remember The Fields Were Added

I am creating a multi-paged form and now i am consulting the Stack guru's for some assistance; On this page the user can add more input fields [type=text] onto the page. So basically there is a singular input for "CHILD NAME" then a Add button to allow the user to add more children if they have more than one.

My form allows you to go backwards and forwards, the form remembers what was input, how would i get jQuery and php to remember that the form fields were added so they are not hidden when the user re-vists the page?

Form Posts But If Fields Are Empty They Overwrite Existing Fields?

I have a form that pulls records for viewing on one page and editing on another. So on the edit page two of the fields (drop downs) that if left empty delete the existing data from the table. All of the other fields retain they're info though.

if (is_null($_POST['field'])) { // skip entry }

Tried it but likely not properly. It breaks the form (and no i didn't include the {//skip entry} Here is a shortened version of the page i'm editing, the two fields that are updating with null are consultantShop and consultantName ->

Extract Info From Html Using PHP(XPath) / Python(Regexp) / Python(XPath)

I have approx. 40k+ html documents where I need to extract information from. I have tried to do so using PHP+Tidy(because most files are not well-formed)+DOMDocument+XPath but it is extremely slow. I am advised to use regexp but the html files are not marked up semantically (table based layout, with meaning-less tag/classes used everywhere) and I don't know where i should start. Just being curious, is using regexp (PHP/Python) faster than using Python's XPath library? Is Xpath library for Python generally faster than PHP's counterpart?

Create A File Upload Form That Creates More Form Fields Based On Input?

I have have ten columns in my SQL table: id, imgid, urlid, image1, image2, image3, image4, image5, and comment. Id, imgid, and urlid are int type. Image[1-5] are mediumblob type. Url and comment are text type. Imgid is the number of images uploaded (max should be 5), urlid is the number of urls submitted (which should be one right now), url holds the url, and comment holds user comments.The form starts by asking the user how many images he wants to upload (max number is 5 in my script). If the user picks, for example, 3, then 3 file upload fields should be created with a new submit button too. A variable called $imgid will store the number 3 which is the number of files the user wants to upload. The user then picks 3 images and clicks the newly created submit button to submit the three images into the first three image columns in the SQL table. My problem is that when I click the second submit button which appears after you click the first one, I get this error:Warning: file_get_contents() [function.file-get-contents]: Filename cannot be empty in dbpform2.php on line 75Here is what I have made so far:

Ajax In Form Then Jquery To Display Filled Form Fields

I have a form that requires a physical address. Once the user enters the full address, I have a button that says "Verify address". I want to be able to click that button, trigger an ajax call that will call a file in the server which will get the longitude and latitude of that address, then return to the form with those coordinates, and display a div with them. Dont worry about figuring out the coordinates. Im just trying to figure out the whole ajax call and jquery display upon response from the server So, I did this;

$(document).ready(function() {
//if verify button is clicked
$('#verify').click(function () {
var address = $('input[name=address]');
var city = $('input[name=city]');
var state = $('input[name=state]');
var zip = $('input[name=zip]');
var country = $('select[name=country]');

process.php returns the longitude and latitude back in a variable as: "longitude,latitude". How do I access that data back in the front end so I can populate the form fields with it?

Post Form Fields Into Array - 'group' Each Form Field

A user can choose a number between 1 and 10 from a list box. Based on the value of their choice I display the same form 1 - 10 times on the page and this form is there to collect personal data. Each form will have a small number of text fields and also some checkboxes e.g:

name (text)
dob (text)
option 1 (checkbox)
option 2 (checkbox)
option 3 (checkbox)

(note the checkboxes should be grouped as an array as they are dynamically built) My question is, how do I 'group' each form field so that when the page is posted (saved) I can capture the correct data for each form filled in? I know arrays are involved somewhere here but not sure how it is implemented.

Using Includes: Html Form Parse Data Inside 2nd Form.

i'm coming down the stretch, so to speak. i've got a lot of the separate things settled that i need for my main "date entry" form. due to the several data items which need to be collected by this form, i've decided to try using includes, which i've found isn't that tricky at all really.

however, one of my includes needs itself to parse it's own little form data to result in the final entry to be submitted in the "date entry" form. perhaps doing this particular bit as an "include" is NOT the best option? Code:

Dynamic Form Fields/multiple Page Form?

It is for a friends out of print booksite, where visitors can request multiple books to be searched by adding one at a time to a cart (javascript), then once all added they submit to another form where they enter their personal details and all is sent through. The problem is at the moment they cannot change whats in the cart without refreshing the browser window and losing everything.

1) present for asking how many books they want to search for
2) display multiple rows of the same input fields depending on how many books they say they want to have searched for?i.e


3) when these are submitted they could see these above the next part of the form where they enter their details with the option to go back and delete/amend.
4) send all the info to my colleague.

if so has anyone seen a similar script that I could take a look @ to see if I can hack it to suit my needs?
