XML - JavaScript - >如何将XML标记显示为HTML

Question

The problem I have is that when an XML node has no value, the open and close tags are on different rows like this

<td ID="ref_4b73aa95ffd2289_phrPayer_1_DateEffective">
</td>
<td ID="ref_4b73aa95ffd2289_phrPayer_1_DateTerminated">
</td>

and when the node has data, the open and close tags are on one line:

<td ID="ref_4b73ba85ffd2289_phrPayer_1_Company">Medicare Parts A&amp;B</td>

The problem I have is that when I read the data, it is read line by line. Following is the XML data that is used:

 <tr>
     <td ID="ref__phrPayer_1_Company">Medicare Parts A&amp;B</td>
     <td ID="ref__phrPayer_1_DateEffective">
     </td>
     <td ID="ref__phrPayer_1_DateTerminated">
     </td>
     <td ID="ref__phrPayer_1_PolicyNumber">
     </td>
     <td ID="ref__phrPayer_1_GroupNumber">
     </td>
     <td ID="ref__phrPayer_1_SubscriberName">AdamJulie</td>
 </tr>

* Above coding consistes of 6 columns, although as displayed above, there are 10 lines of coding. That is the main problem. *

When I try to split up the data into an Array using the following :

var purposeArray = purposeOfVisit.innerHTML.split("\n");

The data I receive is:

Medicate Parts A&B,,,,,,,,,AdamJulie

when it should be:

Medicare Parts A&B,,,,,AdamJulie

The length of the array is the same as the number of lines which is 10 in this case, where it should be 5.

What I want to know is how I read the td tags with the data .

I want the innerHTML to read the folling code as an example:

<td ID="ref__phrPayer_1_Company">Medicare Parts A&amp;B</td>
<td ID="ref__phrPayer_1_DateEffective">
</td>
<td ID="ref__phrPayer_1_DateTerminated">
</td>
<td ID="ref__phrPayer_1_PolicyNumber">
</td>
<td ID="ref__phrPayer_1_GroupNumber">
</td>
<td ID="ref__phrPayer_1_SubscriberName">AdamJulie</td>

instead of:

Medicare Parts A&B
.
.
.
.
.
.
.
.
AdamJulie

The . Represents a null value.

Is this possible and if it is how would I do this? or to replace the <td> tags with &lt;<td> and </td> tags with </td>&lt; ?

Answer 1

Instead of using an XML parser in such a manner , you can read in an xml string via a stream like so:

var XMLString = "<tbody><tr><td ID=''>Medicare Parts A&amp;B</td><td ID=''></td><td ID=''></td><td ID=''></td><td ID=''></td><td ID=''>AdamJulie</td></tr><tr><td ID=''>Test2</td><td ID=''></td><td ID=''></td><td ID=''>123</td><td ID=''></td><td ID=''></td></tr></tbody>";

Where you can split the string after each column:

myXMLArray = XMLString .split("</td>");

And use a regular Expression to remove all tags.

var regex = /(<([^>]+)>)/ig;

for( var x = 0; x < XMLString .length; x++)
{
result[x] = XMLString [x].replace(regex, "");
}

Goodluck...

The innerHTML method returns whatever lies inside the HTML-tag. If you want to fetch the HTML tag with the data, i suggest you use something like:

document.getElementsByTagName('td')

Answer 4

You are trying to write your own XML parser, and you are doing it wrong. You can't simply split XML at line boundaries and then parse each line separately.

There are plenty of good XML parsers available, and it's best to use one of them. If you must parse the XML yourself, then you need to study the art of parser-writing; it's not a job for amateurs.
