Safflower also need green leaf to help--on the purchase of tripod gimbal
Many professional photographers in the purchase of tripods, often generous, 3, 4000 yuan a letter or Manfrotto tripod often do not have to think to buy down, but they are always ignoring the precision of the gimbal is actually, digital camera rack on the tripod on the top of the stability, the decision is the gimbal, So how do we pick a rock-solid gimbal? Gimbal family a wide variety of uses very different simply said, the tripod gimbal is used to connect the camera and the tripod for angle adjustment of the components, mainly divided into three-dimensional gimbal and ball-shaped gimbal. Three-dimensional gimbal in transverse rotation

In the end, the data in summary is much less, and the complete summary content is not always available. Sometimes get garbled, also found on the internet for half a day do not know what the problem caused.
Later discovered that the problem is because Xml_parser parsing XML is the data in the Loop processing node, each time only take about 300 characters length (how much, I am not very clear, just with strlen output about 300), So I know because every time the cycle will be the previous data to the cover, so there will be incomplete data problems.
The solution is to $this->data[the CDATA method in the XML class in the Xml_class file $this->i][$tagname] = $cdata; instead $this->data[$this->i][$ TagName]. = $cdata; ok (there are some notice errors, PHP has been ignored).
