mrtg cfgmaker does read incorrect values over SNMP V1 and V2 and I need to correct the resulting file.
I would like to run a script after creation and use sed if possible.
Lines that needs to be corrected in my case are for LAG's and normal ports:
MaxBytes[switch01_lag_26]: 125000000 should go to MaxBytes[switch01_lag_26]: 250000000
(switch01_lag_26 can be switch01_lag_1 until switch01_lag_26)
MaxBytes[switch01_g1]: 12500000 should go to MaxBytes[switch01_g1]: 125000000
(switch01_g1 can be switch01_g1 until switch01_g16)
What sed patterns I have to use to analyze if its a lag or port in the square brackets and then replace the number after the : ?
The html part should show the correct speed if possible too, this is original for port g1:
<h1>Traffic Analysis for g1-- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>
<td></td>
</tr>
<tr>

<td>1-Gigabit---Level </td>
</tr>
<tr>
<td>ifType:</td>
<td>ethernetCsmacd (6)</td>
</tr>
<tr>
<td>ifName:</td>
<td>g1</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>12.5 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
and should read at the end (Line below "Max Speed" is changed):
<h1>Traffic Analysis for g1-- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>

<tr>

</tr>
<tr>
<td>Max Speed:</td>
<td>125.0 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
This is original for LAG 1:
<h1>Traffic Analysis for lag 1 -- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>
<td></td>
</tr>
<tr>
<td>Description:</td>
<td>lag-1 </td>
</tr>
<tr>
<td>ifType:</td>
<td>IEEE 802.3ad Link Aggregate (161)</td>
</tr>
<tr>
<td>ifName:</td>
<td>lag 1</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>125.0 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
which should read at the end (Line below "Max Speed" is changed):
<h1>Traffic Analysis for lag 1 -- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>
<td></td>
</tr>
<tr>
<td>Description:</td>
<td>lag-1 </td>
</tr>
<tr>
<td>ifType:</td>
<td>IEEE 802.3ad Link Aggregate (161)</td>
</tr>
<tr>
<td>ifName:</td>
<td>lag 1</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>250.0 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
I can change all speeds in HTML using sed -i 's/\([0-9.]\+\) MBytes/125.0 MBytes/' /switch01.cfg but this changes for LAG's too. How to detect if the HTML part belongs to a LAG?

See html below. Have a series of tables that include rows with a name attribute name="laneStop". I can select those rows like this in the Chrome dev console
$x("/html[1]/body[1]//TR[#name='laneStop']")
However, I also need to get the 2nd cell of the 2nd row of the 1st table ABOVE these rows, eg. the value
abc_123_florida-45
Here is the html. Whats a way to refer to this value above - knowing that Im getting the "laneStop" rows first

Try the following xpath.
//td[text()='shipment number']/following::td[1]
Demo:
If you want to travel from your current node (i.e., the "laneStop" rows), one way to do that is to use this xpath expression:
./preceding-sibling::*/ancestor::*[6]/preceding-sibling::table[1]//tr[1]/td[1]/table[1]//td[1]//tr[2]/td[2]
I'm curious to see if it works for you.
Say I get a list of rows like this
var table_stop_rows = (from r in doc.Descendants("TR").Cast<HtmlNode>()
where r.Attributes["name"]?.Value == "laneStop"
select r).ToList();
Now, for each of those "laneStop" rows, I want to refer back to the smaller table containing the "shipment_number" field and read its corresponding node value, eg "abc_123_florida-4". However, I cant simply get a list of all rows where there is a shipment_number, each one has to be in a table that precedes the "laneStop" row in the row collection I'm getting.
I suppose my question then is - if I have a collection of rows, can I then use an xpath statement relative to each row to get back to this shipment_number field in the table preceding?
Here is the html doc, note there would be dozens of these "table pairs". Since I can't control the structure of these files, I need a way to extract the data from the existing structure

Try this xpath expression:
(//tr[#name="laneStop"]/ancestor::table/preceding-sibling::table//tr[2]/td[2])[1]
In the html below, I'm trying to get the two nodes that contain values for shipment_number, but instead I get 6 <td> nodes - why? Doesn't contains limit the nodes to only those that match the text value? If so the statement below should only return two, not six?
In Chrome dev console:
$x("//tr//td[contains(.,'shipment number')]/following::td[1]")

You need
//tr//td[contains(text(),'shipment number')]/following::td[1]
That's because contains(., '...') converts . to string by expanding all its text descendants, not just children.
I'm adding this answer because text() node test might conflict with others requirements, mainly those dealing with inline markup.
The reason because you are getting six td elements is that there is six td having "shipment number" as part of theirs string value (concatenation of all descendant text nodes). And that is because you have nested tables, thus nested td elements. So, you want a td element not having a descendant td element.
The expression:
//tr//td[not(.//td)][contains(.,'shipment number')]/following::td[1]
It selects:
<td>abc_123_florida-45</td>
<td>abc_222_florida-35</td>
Check in http://www.xpathtester.com/xpath/37bd889231ad68bb7bfa377433aeca00
Do note that your input sample has a default namespace declaration with the namespace URI http://www.w3.org/1999/xhtml. Because niether your code sample nor your selected answer are ussing namespaces, I asume you know how to work with them.
I have the following html
<table>
<tr>
<th>value</th>
<th>description</th>
</tr>
<tr>
<td>OverallHealthScore</td>
<td>
Overall HealthScore.
</td>
</tr>
<tr>
<td class="deprecated">DESTAGED_TRACKS_PER_SEC</td>
<td>
The tracks per second saved into disks.
</td>
</tr>
</table>
There are many many tr's but this is an excerpt of the two scenario's
I need to only print out OverallHealthScore
table.css('tr').map do |row|
puts row.css('td:not(.deprecated)').map(&:text)[0]
end
Gets me just about there but prints out the "description" td on the deprecated items. I can't seem to figure out what I need to do in order to get the results I am needing.
Assuming you want to get the first td's value which are not deprecated:
<table>
<tr>
<th>value</th>
<th>description</th>
</tr>
<tr>
<td>OverallHealthScore</td>
<td>
Overall HealthScore.
</td>
</tr>
<tr>
<td class="deprecated">DESTAGED_TRACKS_PER_SEC</td>
<td>
The tracks per second saved into disks.
</td>
</tr>
<tr>
<td>AvaiableAnother</td>
<td>
Another Available HealthScore.
</td>
</tr>
<tr>
<td class="deprecated">OTHER_DEPRE</td>
<td>
The tracks per second saved into disks.
</td>
</tr>
</table>
Then
puts table.css('td:first-child:not(.deprecated)').map(&:text)
# OverallHealthScore
# AvaiableAnother
I have a feed that outputs HTML. The following segment is part of the output
<div class="leftnav">
<table border="0" cols="2">
<tr>
<td colspan="2" class="topline"><span style="font-size: 1px"> </span></td>
</tr>
<tr>
<td colspan="2"><span class="bold">Article Cat1 </span></td>
</tr>
<tr>
<td class="date" colspan="2">
ArticleTitle1</td>
</tr>
<tr>
<td width="20"></td>
<td class="date">
ArticleLink1
</td>
</tr>
<tr>
<td colspan="2" class="topline"><span style="font-size: 1px"> </span></td>
</tr>
<tr>
<td colspan="2"><span class="bold">Article Cat2 </span></td>
</tr>
<tr>
<td class="date" colspan="2">
ArticleTitle2</td>
</tr>
<tr>
<td width="20"></td>
<td class="date">
ArticleLink2
</td>
</tr>
</table>
</div>
I want to process above segment using XPATH so that output looks like this
Article Cat1
ArticleTitle1
ArticleLink1 Article Cat2
ArticleTitle2
ArticleLink2
What is the optimal XPATH that will produce the desired output? I tried //div[#class="leftnav"]/table/tr but this gives all the TR elements. I want to skip the first TR element so that I can get the output in the format I described above.
//div[#class="leftnav"]/table/tr[position() > 1]
Try the above
Stupid simple way:
substring-after(normalize-space(string(//*:div)), normalize-space(string(//*:div/*:table/*[1])))
Result: "Article Cat1 ArticleTitle1 ArticleLink1 nbsp Article Cat2 ArticleTitle2 ArticleLink2"
I don't know why, but (position() > 1) doesn't work in my environment, so I've used strings instead.
