正则表达式中的OR条件

Question

I have table with even & odd row like this

<table id="overviewTable" class="dataTable labelValueTable">
<tr class="even">
  <td class="label">A</td>
<td>
<a href="#">A</a></td>
</tr>
<tr class="odd">
  <td class="label">A</td>
  <td>B</td>
</tr>
<tr class="even">
  <td class="label">A</td>
<td>C</td></tr>
<tr class="odd">
<td class="label">A</td>
<td>D</td></tr>

and I wrote pattern for it like this

@<tr class="(even|odd)">(.*?)<\/tr>@si

but it doesn't work.how can I fix this?

Answer 1

The problem is probably because 'g' is a) not on the list of recognized modifiers and b) redundant with preg_match_all.
