I worked on a project in python using BeautifulSoup for parsing an Html doc and adding ruby and rt tags to each string. Recently I've been working on a similar project for a personal IOS app. I found SwiftSoup which was similar but ran into a problem parsing a tag which I was able to do beautifully using BeautifulSoup. In Beautiful soup I am able to get a tag like the one below
<p id="p6" data-pid="6" data-rel-pid="[41]" class="p6">
<span class="parNum" data-pnum="1"></span>
This is a（<span id="citationsource2"></span><a epub:type="noteref" href="#citation2">link</a>）to some website。
</p>
using .content from BS4 I am able to get the tags into an array like this
['\n', <span class="parNum" data-pnum="1"></span>, '\n This is a（', <span id="citationsource2"></span>, <a epub:type="noteref" href="#citation2">link</a>, '）to some website。\n ']
After i go through the array and check if the children tags have text or if the element in the array is a text element and i just append the ruby tags. The result is this
<p id="p6" data-pid="6" data-rel-pid="[41]" class="p6">
<span class="parNum" data-pnum="1"></span>
<ruby>This<rt>1</rt></ruby><ruby>is<rt>2</rt></ruby> <ruby>a<rt>3</rt></ruby>（<span id="citationsource2"></span><a epub:type="noteref" href="#citation2"><ruby>link<rt>4</rt></ruby></a>）<ruby>to<rt>5</rt></ruby> <ruby>some<rt>6</rt></ruby> <ruby>website<rt>7</rt></ruby>。
</p>
With SwiftSoup I parse the Document doing this since it doesn't have a similar method like the BS4 .content
let soup:Document = try! SwiftSoup.parse(html)
let elements:Elements = try! soup.select("p")
for j in try! elements.html(){
print(try! j)
//Doesn't work prints out every single character not every element
}
The problem is that it treats the whole content of the p tag as an element it doesnt separate the elements in the p tag like BS4 does. I looked at the documentation but I don't see anything about separating the elements from the tag into an array.
This is what I want to achieve with Swiftsoup
['\n', <span class="parNum" data-pnum="1"></span>, '\n This is a（', <span id="citationsource2"></span>, <a epub:type="noteref" href="#citation2">link</a>, '）to some website。\n ']
But end up getting everything as one element in the array instead of seperated elements.
[<span class="parNum" data-pnum="1"></span>This is a（<span id="citationsource2">
</span> <a epub:type="noteref" href="#citation2">link</a>）to some website.]
Is there any way of achieving this using swiftsoup or another swift html parser that could achieve the same thing?
After looking at the SwiftSoup files I was able to find the answer to my question. SwiftSoup has a method called getChildNodes which allows you to get all the content of the specified tag. It returns an array of the content of the tag. Hope this helps anyone who has also faced a similar problem.
let soup:Document = try! SwiftSoup.parseBodyFragment(html)
let p : Elements = try! soup.select("p")
for j in p{
print(try! j.getChildNodes())
}}
I am in need of some help correcting my RegEx string - I have a string of text (A large body of HTML) and I need to take this HTML String and then pattern match it so that data that I have nested within' <div> tags can be extracted and used.
Lets take an example with a test case of <div id=1>
<div id=1>UID:1currentPartNumber:63222TRES003H1workcenter:VLCSKDcycleTime:98.8curPartCycleTime:63.66partsMade:233curCycleTimeActual:62.4target:291actual:233downtime:97statusReason:lineStatus:Productionefficiency:80.05plusminus:-260curProdTime:7/16/2019 12:28:01 PM</div>
What should be noted is that lineStatus can either have a value or be empty such as the same with statusReason
I am able to come up with a regex that does MOST of the work but I am struggling with cases where values are not present.
Here is my attempt:
(
(<div id=(\d|\d\d)>)
(UID:(\d|\d\d))
(currentPartNumber:(.{1,20}))
(workcenter:(.{1,20}))
(cycleTime:(.{1,6}))
(curPartCycleTime:(.{1,6}))
(partsMade:(.{1,6}))
(CycleTimeActual:(.{1,6}))
(target:(.{1,6}))
(actual:(.{1,6}))
(downtime:(.{1,6}))
((statusReason:((?:.)|(.{1,6}))))
((lineStatus:((?:.)|(.{1,6}))))
(Productionefficiency:(.{1,6}))
(plusminus:(.{1,6}))
(curProdTime:(.{1,30}))
)
Split it up just for readability.
Thanks,
You are very, very close.
If you use:
(
(<div id=\d{1,2}>)
(UID:\d{1,2})
(currentPartNumber:(.{1,20}))
(workcenter:(.{1,20}))
(cycleTime:(.{1,6}))
(curPartCycleTime:(.{1,6}))
(partsMade:(.{1,6}))
(CycleTimeActual:(.{1,6}))
(target:(.{1,6}))
(actual:(.{1,6}))
(downtime:(.{1,6}))
(statusReason:(.{0,6}))
(lineStatus:(.{0,6}))
(Productionefficiency:(.{1,6}))
(plusminus:(.{1,6}))
(curProdTime:(.{1,30}))
(<\/div>)
)
Then $3\n$4\n$6\n$8\n$10\n$12\n$14\n$16\n$18\n$20\n$22\n$24\n$26\n$28\n$30 will be:
UID:1
currentPartNumber:63222TRES003H1
workcenter:VLCSKD
cycleTime:98.8
curPartCycleTime:63.66
partsMade:233cur
CycleTimeActual:62.4
target:291
actual:233
downtime:97
statusReason:
lineStatus:
Productionefficiency:80.05
plusminus:-260
curProdTime:7/16/2019 12:28:01 PM
By using (statusReason:(.{0,6}))(lineStatus:(.{0,6})) you make the value of statusReason and lineStatus truly optional.
I also simplified the start <div> and UID detection.
Try Regex: ((<div id=(\d|\d\d)>)(UID:(\d|\d\d))(currentPartNumber:(.{1,20}))(workcenter:(.{1,20}))(cycleTime:(.{1,6}))(curPartCycleTime:(.{1,6}))(partsMade:(.{1,6}))(CycleTimeActual:(.{1,6}))(target:(.{1,6}))(actual:(.{1,6}))(downtime:(.{1,6}))(statusReason:(.{1,6})?)(lineStatus:(.{1,6})?)(Productionefficiency:(.{1,6}))(plusminus:(.{1,6}))(curProdTime:(.{1,30})))

If I have a template like this:
<div class="lift:ThisIsMySnippet?option1=a_value;option2=another_value">
<div class="morestuff">
{embed}
</div>
</div>
and then a snippet like this:
class ThisIsMySnippet {
// I want option1's value!
}
How do I get those values?
I believe you can get the param values of a snippet via the S object like this:
val x = S.attr("option1")
In this case, x will be a Box[String], so if you want to get the value in a safe way you could do this:
val x = S.attr("option1") openOr "defaultValue"
Is there a way I can modify dynamically the param of a snippet?
E.g. If I call this URL
host:port/a_page?name=myname
I would like that my page look like this:
<div class="lift:surround?with=default;at=content">
<div class="lift:comet?type=MySnippet;name=myname" >
...
</div>
</div>
Is that even possible? I tried using some javascript in order to extract the param from the url and putting it in the class attribute of the div but in my understanding that won't work becase the scripts will always execute after lift framework does it's magic.
Thanks in advance! Any help is really appreciated.
I used both tips provided to make it work, like ajantis mentioned reading the param directly from snippet is the easiest way but doesnt work in a comet call. Rogach solution works.
So the solution is:
<div class="lift:Ex.wrap">
<div id="myid"></div>
</div>
def wrap = {
val name = "lift:comet?type=MySnippet;name=" + S.param("name").openOr("...")
"#myid" #> <div id="myid" class={name} ></div>
}
Why not just extract http parameter inside snippet processing? i.e.
def render = {
val name = S.param("name").openOr("...")
....
}
You can try wrapping that comet snippet in other snippet, which would transform xml and add that name=myname to class. Like:
<div class="lift:Ex.wrap">
<div class="lift:comet?type=MySnippet"></div>
</div>
class Ex {
def wrap = { (n: NodeSeq) =>
// example transformation
// AntiXML syntax
import com.codecommit.antixml._;
val comet = n \ "div" head;
val comet2 =
comet.copy(attrs = comet.attrs +
("class" -> (comet.attrs("class") + ";name=myname")))
n \ "div" updated (0, comet2) unselect
}
}
I am trying to get the value of the data item to use in a {{if}} tag, but cannot get it to work. So, the question is how do we get that value? You can see full code here http://jsfiddle.net/epitka/BhYvh/
<script id="contentHeaderTemplate" type="text/x-jquery-tmpl">
{{if($data.Id===1)}} Create New Order{{else}}Edit Order {{/if}}
<br />
</script>
Drop the parentheses.
{{if $data.Id === 1 }}
http://jsfiddle.net/mattball/KdqZF/
See also the {{if}} template tag API page.
You don't need the parentheses in that if statement. Try:
{{if $data.Id === 1 }}
