ios - hpple XPath query for complex html

I have a complex html file that I need to parse in Objective-C. The html looks like

<HTML>
<TABLE width="100%" border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td width="10" align="left" valign="top"><img src="http://www.indianrail.gov.in/main_text_left_top2.gif" alt="" width="8" height="8"></td>

You can locate table rows with this:

List<WebElement> tableRows = findElements(By.xpath("//TABLE[@class='table_border_both_left']//tr[not(@class='heading_table_top')]"));

In a row find the expected data :

for (WebElement row : tableRows) {
    String trainNo = row.findElement(By.xpath("td[1]")).getText();  //or use xpath : td[1]/text()
    String origin = row.findElement(By.xpath("td[3]")).getText();     //or use xpath : td[3]/text()
    String deptTime = row.findElement(By.xpath("td[4]")).getText();     //or use xpath : td[4]/text()
    String destination = row.findElement(By.xpath("td[5]")).getText();     //or use xpath : td[5]/text()
    String arrTime = row.findElement(By.xpath("td[6]")).getText();     //or use xpath : td[6]/text()

    List<WebElement> radioButtons = row.findElements(By.xpath("td//input[not(@name='lccp_trndtl')]"));
    // or use xpath : //TABLE[@class='table_border_both_left']//tr[not(@class='heading_table_top')]//td//input[not(@name='lccp_trndtl')]//@value

    for (WebElement radio : radioButtons) {
        String value = radio.getAttribute("value");
    }
}

Sorry for my code but I'm using Selenium WebDriver in Java. I hope the given xpath expressions will be useful.
